[[caption-width-right:350: [-The [[DepartmentOfRedundancyDepartment coolest]] Cool Gate there is. [[EverythingsBetterWithSpinning It even spins]], for added [[OverlyLongGag coolness]]... [[ForTheLulz 'Cause it's cool!!]]-] ]]

''It’s a great big world,''\\
''With a great big swirl that you step inside to another world.''\\
''We’re talking Stargate,''\\
''It’s a crazy trip,''\\
''You can go quite far and you don’t need a car or even a ship.''
-->-'''Joe Mallozzi''', '''Paul Mullie''', and '''Peter [=DeLuise=]''' ''singing the lyrics they invented for the ''Series/StargateSG1'' intro music''.

First you're ''here''. Walk through this here gate—possibly only when the moon is gibbous, or you have yellow violets in your left hand, possibly only with the AppliedPhlebotinum and TechnoBabble of quantum mechanics or [[OurWormholesAreDifferent folding space-time]] or maybe even [[FunctionalMagic magic]]—and then you are... ''there''.

[[TitleDrop Cool, ain't it]]?

Unlike CoolCar, CoolBoat, etc., this is not about distinctly cool gates. Gates tend to be rare enough that they are ''all'' cool. Even when they interconnect into a PortalNetwork.

This is a common way of getting to MagicalLand. After all, even the coolest of airplanes and boats have a little trouble with the travel there; subtropes include PortalPool, PortalDoor, and PortalPicture.

It's also common in ScienceFiction.

Be warned that there is no guarantee of pleasantness or even familiar physics on the other side. AlienGeometries are not unknown.

After a time, PortalSlam may result, or it [[PortalCut may close when in use]].

Since there's no real-world analog to teleportation, writers can apply any variety of bizarre special effects to the act of being transported without hurting WillingSuspensionOfDisbelief. On the other hand, they can also appear relentlessly mundane—perhaps a simple arched doorway in a wall of crumbling stone—until you look or step through them, and notice the discrepancy.

Note that this does ''not'' encompass characters who can transport themselves without crossing the intervening distances, or mere holes that create space. TeleportersAndTransporters also do not cover it even if one end must have certain equipment to it. It may overlap OurWormholesAreDifferent.

Has nothing to do with [[{{Scandalgate}} media or political scandals being referred to with a reference to "Watergate"]] or with [[IncrediblyLamePun a particular brand of toothpaste]].

* In one of the later Manga of ''Manga/AhMyGoddess'' we get to ''meet'' the gate between Earth and Heaven, and she's a kinda cute kinda loli creepy girl. One that wants to have some fun and won't open for anyone till she's had some. Eventually, Keiichi is dragooned into opening her, with a (big) key, DoesThisRemindYouOfAnything
** In the movie, there is also a magic gate that only true lovers could pass through and still remain together. Guess what happened.
* One of ''Anime/{{Doraemon}}'''s recurring [[MacGuffin tools]] is the "Anywhere Door", which when walked through brings you to any location you tell it, as long as you made sure you [[LiteralGenie worded your request carefully]].
* ''Manga/MahouSenseiNegima'' has the Gateports to the [[MagicalLand Magic World]]. One of them is underneath TheWorldTree, another is ''Stonehenge''.
* The entrance to C's world is some sort of psychic stone wall in ''Anime/CodeGeass''.
* In ''Anime/{{Naruto}}'', Sakon/Ukon and Orochimaru can both summon a demonic version of the main gate to Kyoto to block attacks.
* The gate in [[spoiler:Myotismon's castle]] from ''Anime/DigimonAdventure'' is used in reverse: it doesn't take you to MagicalLand but ''from'' it. (In fact, it can take you to ''any'' dimension so long as you know how to properly arrange the cards.)
** In Anime/DigimonAdventure02, any computer with a D3 [[AppliedPhlebotinum Digivice]] held up to it. (The old-school digivice used by the original team could only access the Digital World from certain computers at certain times. If the gate closes, you're out of luck. The new kids can come and go at will, though.)
* The Gates Of Justice in ''Manga/OnePiece'' that connect Enies Lobby, Impel Down and Marineford qualify for this-they are hundreds of meters tall and several meters thick.
* ''Manga/BlueExorcist'': The Gehenna Gate which is like a sort of EldritchAbomination in its own.
* Johan reveals in Season 3 of ''Anime/YuGiOhGX'' that Duel Monsters cards aren't like [[Franchise/{{Pokemon}} Pokeballs]] that contain and release monsters but are actually the gates monsters use to travel between their world and their master's.
* ''Literature/{{Gate}}'' that is about a [[ExactlyWhatItSaysOnTheTin gate]] from Japan to a medium-fantasy world.

[[folder:Card Games]]
* The ''TabletopGame/YuGiOh'' card game happens to have multiple takes on this, including 'Different Dimension Gate', 'Monster Gate', and even a card meant to restrict attacks, "The Dark Door", which takes the form of a CoolGate (or at least a door out of a very freakish universe).
* MagicTheGathering provides us with [[http://gatherer.wizards.com/pages/card/Details.aspx?multiverseid=73559 Door To Nothingness,]] a cool gate to a [[CessationOfExistence non-cool place]].

* For a while the ''Comicbook/XMen'' were the proud owners of the Siege Perilous (named for the Arthurian myth), a magical portal which shrunk down to handy portable size. Passing through it would reboot your life (and give you amnesia along the way).
** And there's a Shi'Ar Stargate at the edge of the solar system. Don't tell anyone, though, because using it can ''[[ApocalypseHow destabilize the Sun]]''. The Shi'Ar also use smaller personal Gates.
* Under WonderWoman's home island Themyscira is a gate to Hades, at least in ComicBook/PostCrisis continuity and on the ''WesternAnimation/JusticeLeague'' cartoon.
* ''ComicBook/TheAuthority'' can call the Carrier for a Door to anywhere in the world, or back to the Carrier, and at least once to parallel universes.
* ''ComicBook/TheSandman'' has several magic gates. Each of the Endless has a gallery which they use to talk and visit each other's realms. In the real world, any labyrinth can be used as a gate to Destiny's realm. Destruction creates a gate (with an appropriate big explosion) that Orpheus uses to visit Death's realm. Dream's realm has an ornately carved big gate at the front which dreams pass through.
* The Creator/GrantMorrison era of ''Franchise/{{Justice League|of America}}'' has Portal Gates like this at certain times that seemed to link the JLA moonbase to a few key locations. Not used very often (at least "on screen").
* In the ''Franchise/StarWars'' comics, they introduce the [[http://starwars.wikia.com/wiki/Infinity_Gate Infinity Gates]] [[AncientArtifact built by]] the Kwa using the [[AppliedPhlebotinum technology of]] [[{{Precursors}} the Celestials]]. Apparently, there was a [[PortalNetwork network]] that allowed instantaneous travel nearly anywhere in the galaxy. Oh and for added fun, they could be used as devastating [[WaveMotionGun superweapons]], projecting [[http://starwars.wikia.com/wiki/Infinity_Wave Infinity Waves]] which [[ThereIsNoKillLikeOverkill destroyed all life and matter at the target]] and made hyperspace travel impossible in its vicinity.
* Boom Tubes in the ''ComicBook/NewGods'' mythos. They can be summoned anywhere with a Mother Box computer, and are in general used by the Gods on a regular basis.
* Played for laughs a lot of times in ''ComicBook/MortadeloYFilemon'', as the way the two agents often go to the T. I. A. headquarters -and expect someone attempting the same after both have entered, just to fail miserably.- Examples include them entering into a traffic signal by opening it, ''into the Sun'' one lifting the other as if it was just a window, and entering into an open coffin, complete with a corpse, in a funeral parlour.

* ''FanFic/SplitSecond'' has [[spoiler:[[TheGrimReaper Death's]]]] ''wings'' as a portal to the afterlife.

[[folder:Films -- Animation]]
* The door leading out of ''Anime/HowlsMovingCastle''.
* In ''Disney/TreasurePlanet'', it turns out this is how Flint managed to plunder so many planets.
* When activated, the Doors in ''WesternAnimation/MonstersInc'' connect the monster's world to children's bedrooms throughout the human world. When inactive, they are ordinary doors connecting the bedrooms to closets, etc. That is why the monster is never there when your parents open the door to check.

[[folder:Films -- Live Action]]
* The Digital Gate in ''Film/{{TRON}}''.
* ''Film/{{Phantasm}}'': The gate in the mausoleum consisted of two metal poles stuck in the floor. Anything that passed through them went to the planet which the Tall Man came from.
* ''Film/{{Poltergeist}}'': The ghosts who are haunting the house creates a gate in the children's closet leading to the other side: another gate in the ceiling of the living room leads back to our world.
* ''Film/{{Stargate}}'' provides our page image.
* The TannhauserGate was merely mentioned once in ''Film/BladeRunner'', and its function not even described, but MemeticMutation has made it a CoolGate nonetheless.
* In ''Film/TheNeverendingStory'', Atreyu passes through a mirror that serves this purpose.
* In ''TimeBandits'', the characters rely on a map to locate gates that lead to various points in time and space.
* ElSanto's time machine (of ''course'' he can build a time machine!) in ''Film/SantoEnElTesoroDeDracula'' is basically a cheaper-looking version of TV's ''Series/TheTimeTunnel''.
* In ''Film/{{Beetlejuice}}'', when you're dead, drawing a door on a wall will open a path to a wonderland of dreary bureaucratic waiting rooms. Which is still better than if you walk out of the location you're stuck haunting...
* There are nine gates in the title sequence of Polanski's ''Film/TheNinthGate'', made all the more portentous by Wojciech Kilar's score.

* In ''Literature/TheCatastropheOfTheEmeraldQueen'', the magical teleportation device called the Shimmer. Powered by crystals and activated by stepping into a dip in a stone floor. The effect is described as like watching a stone being dropped into water. Can also be rigged or tampered with to enable users to arrive helpless.
* In ''Literature/TheDresdenFiles'', wizards and others practitioners of magic are able to open a hole into the Nevernever (usually the LandOfFaerie, the region closest to the physical world), an alternate dimension where physics, geometry, and time don't always work the way they do here. The upside? Rapid transportation for wizards, especially since their magic [[WalkingTechbane makes mundane travel hard]]. The downside? The wizard has to hold it open, and even powerful wizards can only open small holes. It takes a very powerful wizard (Harry's caliber or so) to be able to open a crossing in more than a few places to begin with. And while the Ways are great for getting places, the Nevernever is also where most of the {{Eldritch Abomination}}s live.
* The door in Creator/DanAbnett's ''Literature/{{Ravenor}}'', a plain wooden door that opens through space and time. Originally, it used by special trained operators, to let the questions of those who came to them direct it; when the house was broken, Ravenor operated it to put his powerful psionic abilities into play.
* In Creator/DanAbnett's ''Literature/GauntsGhosts'' novel ''His Last Command'', Chaos warp gates open up in boulders to let out monsters. When Maggs is thrown through one, and [[NoOneGetsLeftBehind Mkoll jumps after him]], they find a [[EvilIsDeathlyCold frigid]], [[AlienGeometries impossible landscape]] with [[AlienSky the stars all wrong and blocks of stone floating in the sky]]. They stagger to another gate, which lands them at the foot of another boulder, both of them covered with frost (on the other side, they communicate back through the vox, though it finds them both out of range and within ten kilometers at once).
* In the ''Literature/MythAdventures'' series, Skeeve's tiny tent leads into a huge luxurious mansion. The mansion is actually in another dimension, which occasionally leads to some problems.
* Creator/LewisCarroll's ''[[Literature/AliceInWonderland Through the Looking Glass]]''. Mirrors are frequently used as portals to other realms. There's just something about mirrors...
* In Creator/CJCherryh's ''Literature/MorgaineCycle'', the planet-based gates allow both interstellar and TimeTravel. Not to mention [[GrandTheftMe body-switching]]. Also, any TimeTravel leading to a TimeParadox triggers a TimeCrash which wipes out civilization on every planet containing a gate, which is why Morgaine is on a quest to shut down the PortalNetwork.
* Susan Cooper's ''Literature/TheDarkIsRising'' series. Powerful Old Ones (such as Merriman Lyon) are able to summon a magical gate (which looks like a pair of doors) that allows travel through time and space.
* John [=DeChancie=] likes this trope; his ''Literature/CastlePerilous'' has 144,000 doors, each leading to an AlternateUniverse, and they don't just wait for you to walk through—the portals wander, and actively seek out those who want to travel or get away. His ''Skyway'' series has "Tollbooths" (no doubt named as a ShoutOut to ''Literature/ThePhantomTollbooth'') which use miles-tall columns of virtual particles to create [[OurWormholesAreDifferent wormholes]] linking a vast Road across thousands of planetary surfaces.
* In ''Literature/TheRedemptionOfAlthalus'' by Creator/DavidEddings, the protagonists live in a house with as many rooms as they like, as large as they like (they occasionally have armies on the march through the corridors) and can open doors to literally anywhere on command. One of the protagonists attempt, out of curiosity, to open a door to "nowhere"—although they avert the attempt before they succeed, the concept is enough to freak out their patron goddess something fierce.
* Creator/PhilipJoseFarmer's ''Literature/WorldOfTiers'' series. Inter-dimensional machines/gates.
* There's a magical hole in the wall of some sort in ''Literature/{{Coraline}}'', by Creator/NeilGaiman.
* The interstellar gates in Creator/RobertAHeinlein's novel ''Literature/TunnelInTheSky''.
* In P.C. Hodgell's ''Literature/ChroniclesOfTheKencyrath'', Mother Ragga (an [[ElementalPowers Elemental Personification]]) has a house whose doors can open, it seems, anywhere in the world.
* The door leading out of the title castle in Creator/DianaWynneJones's ''Literature/HowlsMovingCastle''.
* ''Literature/TheWheelOfTime'' has them in at least three flavors:
** The redstone doorways look like empty doorframes, but walking through one will transport you to a dimension populated by [[TheFairFolk weird aliens]] who see the future or grant wishes.
** The Waygates, built of finely carved white stone and having nice reflection visual effect, which lead to a [[SubSpaceOrHyperspace place where the distance between the Gates is less than outside]]
** The One Power-created Gateways for Skimming (travel via subspace) and Traveling (instant teleportation).
** There are also Portal Stones, which are ExactlyWhatItSaysOnTheTin. They link not only to other portal stones in the world, but also to Portal Stones in Parallel worlds. Very handy, if not well understood at all.
* The title tollbooth of Norman Juster's ''ThePhantomTollbooth''.
* ''Literature/TheForgottenDoor'' by Alexander Key. An inter-dimensional machine/gate.
* In Creator/MercedesLackey's ''Literature/HeraldsOfValdemar'' series, the Gate Spell reaches across the VoidBetweenTheWorlds in order to provide instantaneous travel from one physical place to another. The spell has a number of important limitations; each Gate is a single-use construction created by a powerful mage [[CastFromHitPoints using his own life force]], must be built with both ends in a doorway or similar structure (frames often used for Gates are attuned to the proper energies and are easier to use), and can only go somewhere said mage has been to and knows well. The ancient Adepts of the Mage Wars, on the other hand, knew the secrets of Permanent Gates, which once created are simple to activate and use. From what we see of the mysterious [[TheEmpire Eastern Empire]], it has overcome all the limitations of Gates, to the point of building them into a {{Magitek}} society and using them to control vast swaths of territory. This poses a major problem for the Empire when TheMagicGoesAway.
* Reality Thresholds are pretty much the driving force behind the entire book in ''Literature/DarknessVisible''. Venturers can tear holes in the fabric of reality with their bare hands and, if they're focusing properly, simultaneously open a second Threshold in another location, allowing them to step instantly between the two places. If they aren't focusing properly, [[GoMadFromTheRevelation bad things]] happen... Deliberately abusing Thresholds may lead to even [[UpToEleven worse]] things [[TheEndOfTheWorldAsWeKnowIt happening]].
* ''Literature/TheChroniclesOfNarnia'':
** The wardrobe in ''Literature/TheLionTheWitchAndTheWardrobe''..
** The {{Portal Pool}}s in the Wood Between the Worlds in ''Literature/TheMagiciansNephew'', the door to the Telmarines' original home at the end of ''Literature/PrinceCaspian'', the PortalPicture in ''Literature/TheVoyageOfTheDawnTreader'', the door that normally led to the open moor in ''Literature/TheSilverChair'', and the door that normally led to the stable in ''Literature/TheLastBattle''. '''All''' the books except the one that took place exclusively in Narnia needed magic gates, because the characters were from another universe (the real one).
* In Lee Lightner's ''TabletopGame/{{Warhammer 40000}}'' Literature/SpaceWolf novel ''Sons of Fenris'', Cadmus's BloodMagic lets him open a portal to a Chaos SpaceMarine.
** In ''Wolf's Honour'', they conclude that [[spoiler:the entire planet is riddled with gates, allowing the Chaos {{Space Marine}}s to invade at will]].
* In Creator/PatriciaAMcKillip's ''Literature/TheBellAtSealeyHead'', Emma keeps opening doors and finding Princess Ysabo. She never dares go in for fear that she can't come back. And one day when she opens the door to her grandmother's room, it shows the princess in a different room. She closes it, reopens it, and finds her grandmother's room.
* In Creator/GrahamMcNeill's ''TabletopGame/{{Warhammer 40000}}'' ''Literature/{{Ultramarines}}'' novel ''Dead Sky Black Sun'', when Sergeant Ellard confesses to having actually seen the rumored daemon on a battle field, he explains that in the end, it summoned up a black gate and vanished into it.
* Creator/AndreNorton's ''Literature/WitchWorld'' has dozens of these.
** How Simon Tregarth got there in ''Witch World''
** Where the Kolder had come from.
** Where Simon and Jaelithe vanished to, and Kaththea found them and Hilarion.
* ''Literature/HisDarkMaterials'', as if to fight back against Narnia listed above, has a knife that can make a gate anywhere by ''cutting holes in the fabric of the universe''. Unfortunately, it has the [[PoweredByAForsakenChild nasty side effect]] of unleashing soul-eating beings of nothing whenever it's used.
* Creator/JamesHSchmitz set ''[[Literature/TelzeyAmberdon The Lion Game]]'' on a planet in the Hub where all transportation was done by gates. The villains in that story have another CoolGate -- the Vingarran Gate is too long-range to be useful on the planet surface, but it's ideal for them to transfer people to and from their spaceships hiding in the outer reaches of the solar system.
* Looking glass bosons, in the Creator/JohnRingo (and later Creator/TravisSTaylor) series ''Literature/IntoTheLookingGlass'' (with {{shout out}}s a-plenty to the other looking glass portal, mentioned above).
* The Manticore Wormhole Junction, and similar junctions elsewhere, in the ''Literature/HonorHarrington'' novels.
* ''The Green Door'' in Creator/HGWells' short story of the same name.
* In Creator/PatriciaCWrede's ''[[Literature/EnchantedForestChronicles Talking to Dragons]]'', Morwen has one door to all the rooms in her house. When it keeps giving Daystar the wrong ones, she tells him he has to be firm.
* The novelization of the ''Literature/{{Doom}}'' series had the Gate to "Hell" actually be a matter transmitter leading to aliens who used psychological warfare, by imitating feared images from humanity's collective unconscious. But, unlike most fictional interstellar teleportation, it was ''not'' faster than light.
* The Veil in the Department of Mysteries that claimed [[spoiler: Sirius]] is an example of such a portal from ''Literature/HarryPotter''.
* In Sergey Lukyanenko's ''Literature/RoughDraft'' series, the portals to {{Alternate Universe}}s are shown as regular doors, although they can only be opened by the customs officer-Functional who lives at the customs office. This, as well as the abilities of the Functionals, is explained by their advanced understanding of quantum physics.
* The ''Literature/YoungWizards'' series has "world gates", small patches of space-time only visible to wizards, which occur naturally but can also be created by magic or very advanced technology. Though wizards can teleport without world gates, using a gate requires much less energy, especially for trips that are measured in light-years. On Earth world gate complexes are maintained by teams of cat wizards, since cats are the only Earth species which is naturally capable of seeing the [[http://en.wikipedia.org/wiki/String_theory string structures]] which the gates are made from.
* One means of getting around in the endless world of ''Literature/TheNeverendingStory'' is [[ExactlyWhatItSaysOnTheTin The Temple of a Thousand Doors]] (Der Tausend-Türen-Tempel) which contains an infinite number of hexagon-shaped rooms with three doors each. Every door different in colour, shape, material etc. To get to the place you wish to go, you only need to pass through the rooms until you find the door that reminds you strongest of the thing/place/person you're looking for. This may take some time.
* In ''Literature/{{Spin}}'' there is the Arch, a gigantic structure connecting to another planet.
* The portable door in ''Literature/ThePortableDoor'' by Tom Holt. A door-shaped sheet of something that can be rolled up, but when put against a wall will open to the desired location.
* In Creator/StephenKing's ''Franchise/TheDarkTower'', Roland discovers a series of doors which allow him to look into other worlds, possess a specific individual on the other side when he steps through the door, and pull that person back through the door into his own world. This is how he eventually gathers his three traveling companions who follow him in the later books.
* In Creator/NeilGaiman's ''Literature/{{Neverwhere}}'', Door opens doors. All doors. Her family house had its locations all over the place because they could open the doors between them.
* The Farcasters connecting the [=WorldWeb=], in Dan Simmons' ''Literature/HyperionCantos''.
* Doors that open to distant locations, times, and/or realities are a dime a dozen in the {{Literature/Nightside}} series, and one minor character even operates a business where people can pay to pass through any of the hundreds of CoolGate doorways he's stocked his shop with.
* The [[ExactlyWhatItSaysOnTheTin Great Door Of Time]] in ''Literature/SeptimusHeap''.
* In Creator/DevonMonk's ''Literature/DeadIron'', what [=LeFel=] is trying to build.
* The Flumes in "Literature/ThePendragonAdventure".
* In Creator/AndreNorton's ''Literature/DreadCompanion'', Bartare opens one to transport them from the planet.
* ''Literature/ThePowerOfFive'': The Gates that keep the Old Ones at bay are kinda cool, once you look past how terrifying the entire concept is.
** On a considerably less scary note, there are also the 25 doors with blue star symbols which allow the Five and up to one other each to travel to any one of their choosing.
* Twilight gates from the setting of ''[[Literature/{{Somewhither}} A Tale of the Unwithering Realm]]''. They're golden ring-shaped portals whose rims have the form of three-dimensional Mobius strips, and when they are active a rainbow of colors and a spherical light-bending interdimensional rift appears in the middle.
* Stonemover's portals from ''Literature/WingsOfFire'', which connect the Rain kingdom and Sand kingdoms with each other [[spoiler:and also with the Night kingdom.]]


[[folder:Live Action TV]]
* Jumpgates in ''Series/BabylonFive'' are used to enter and exit [[SubspaceOrHyperspace hyperspace]].
* In the ''Series/DoctorWho'' episode "The Girl in the Fireplace", clockwork androids from the future use the hyperspace drive of a spaceship to create temporal gates disguised as mirrors, tapestries and fireplaces to stalk Madame de Pompadour's lifespan, finding the proper moment in her life to take her.
* ''ForeignExchange'' is about a portal between Perth and Galway. The writers started ignoring the time difference after a few episodes.
* ''Series/{{Lost}}'': turning the wheel under the Orchid moves the island and teleports the wheel-turner to the Tunisian desert.
* The comedy-fantasy ''MisterMerlin'' has a door in Merlin's house that lead to a magical realm.
* ''Series/TheOuterLimits1963'' episode "The Borderland". Scientists generate a gate to another dimension.
* The StargateVerse, source of our page image. ''Series/StargateSG1'', ''Series/StargateAtlantis'', and ''Series/StargateUniverse'', [[http://images1.wikia.nocookie.net/__cb20100221045633/stargate/images/b/bf/Stargate.JPG All]] [[http://i.imgur.com/o5WN83b.jpg four]] [[http://images3.wikia.nocookie.net/__cb20091115192114/stargate/images/c/c5/DestinyGateEarth.jpg of]] [[http://images1.wikia.nocookie.net/__cb20100221050230/stargate/images/7/75/Supergate_vortex.jpg 'em]] had the title gates be as cool as possible.
* ''Series/StarTrekTheOriginalSeries'':
** Episode "All Our Yesterdays". The Atavachron, a gate to the past.
** Episode "Assignment Earth". Gary Seven's "mist gate" transporter.
** Episode "The City on the Edge of Forever". The time travel sentient stone ring called The Guardian of Forever.
* The Iconian Gateways seen in ''Series/StarTrekTheNextGeneration'' and ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]''.
* The [[OurWormholesAreDifferent Wormhole]] from ''Series/StarTrekDeepSpaceNine''.
* In ''Stranger Things'' the monster can seemingly turn any surface into a gate between the normal world and the Upside Down.
* The titular device from ''Series/TheTimeTunnel''.
* ''Series/TheTwilightZone'' TOS episode "Little Girl Lost''. The title character accidentally falls through a spontaneously appearing gate in the wall of her room and ends up in another dimension. Her parents and a family friend try desperately to get her back before the gate closes.
* In the ''Series/{{Kaamelott}}'' episode "[[ShoutOut Stargate]]", a "Gate of Chaos", through which "the worst possible creatures" are going to arrive, is opened in Kaamelott. Arthur and Lancelot investigate, Bohort panics until... Perceval steps through. And then a chicken flies through. It turns out the gate leads to another part of the castle.
* First, you see something like shattered glass floating in the air. Next thing you know, you are being chased by a velociraptor. Welcome to ''Series/{{Primeval}}''.
* ''Series/{{Angel}}'' has portals to Pylea. They can only be opened at [[LeyLine psychic hotspots]] and can't be opened too many times.
* ''Series/TheLegendOfDickAndDom'' has an episode, "Valley of the [[MyBrainIsBig Bigheads]]", where the heroes want to use a CoolGate guarded by the Bigheads; to be allowed to use it, they need to prove they are geniuses, which is rather [[IdiotHero difficult]] for them. It turns out the gate [[spoiler: only transports you ten yards further along the road, and the Bigheads only bother to guard it]] [[LaughablyEvil for lulz]].
* ''Series/KamenRiderFourze'' has an ''ordinary school locker'' which connects to a base on the moon.

* The movement ''The Great Gate of Kiev'' (in Russian ''Богатырскія ворота (Въ стольномъ городѣ Кіевѣ)'', meaning ''The Bogatyr Gates (in the Capital in Kiev)'') from Modest Mussorgsky's magnum opus ''Pictures at an Exhibition''.

* ''Pinball/{{Varkon}}'' features a stone gate through which the monstrous Varkon can be seen. Playing well on the main table enables the lower level, allowing players to attack Varkon on the other side.
* The ''Pinball/{{Stargate}}'' pinball has the titular gate as the centerpiece of the backbox, using a mirrored "infinity" effect to give the illusion of entering it.
* The "transphazers" of ''[[Pinball/TXSector TX-Sector]],'' which are used to teleport pinballs across the playfield.

[[folder:Tabletop Games]]
* ''[[TabletopGame/DungeonsAndDragons Dungeons & Dragons]]''
** The portals of the ''TabletopGame/{{Planescape}}'' setting.
** The TabletopGame/ForgottenRealms have many magical Gates, most of which are (naturally) forgotten.
** The Gate of the Silver Keys in adventure X2 ''Castle Amber", which leads to the land of Averoigne on another plane.
** Module Q1 ''Queen of the Demonweb Pits''. A temple in a Drow city has a mural of a starry sky which is a Gate. If the [=PCs=] pass through an image of Lolth and touch it, they will be transferred to the level of the Abyss where Lolth's Demonweb exists.
* The Necrons of ''TabletopGame/{{Warhammer 40000}}'' use portal technology to teleport with impunity. Chaos forces occasionally use portals of their own to access the [[HyperspaceIsAScaryPlace Warp]] without waiting for a NegativeSpaceWedgie.
** Creator/SandyMitchell's Literature/CiaphasCain[[note]]'''HERO OF THE IMPERIUM!!!'''[[/note]], cornered by Necrons and wounded, took the [[RefugeInAudacity one route they had not expected]]: he jumped through their gate, having seen a wounded Necron come through it and guessing there were friends on the other side.
* ''TabletopGame/CallOfCthulhu'' has spells that create Gates through time or space.
* ''TabletopGame/EclipsePhase'''s [[MeaningfulName Pandora Gates]], leftovers of TheSingularity and the only current method of reaching planets outside the solar system.
* ''TabletopGame/FadingSuns'' has Jumpgates, ancient relics created by the mysterious [[{{Precursors}} Annunaki]]. They they form the [[PortalNetwork Jumpweb]] that allows Humanity to travel from planet to planet, connecting Known Space.
* While not shaped like gates in the conventional sense, every Pantheon in ''TabletopGame/{{Scion}}'' has an Axis Mundi, something that links that Pantheon's Godrealm to the World that's tied to their myth or their people's culture. As examples, the Aesir use Yggdrasil to get between Asgard and any ash tree on Earth, while the Amatsukami use the Pillar of Heaven to get into the Overworld from anywhere that Japanese culture is strong.
* ''Fringeworthy'' (1982) was built entirely around this trope: {{PC}}s were members of a UN military exploration force, walking from world to world through circular portals left by an alien race millions of years before.
** Rumor has it that a copy of the game was given to the writers of [[Film/{{Stargate}} a certain motion picture]] on the assumption that "Tri-Tac is out of business, and besides, our lawyers are bigger."
* ''TabletopGame/{{Exalted}}'' has bits of First Age technology called the Gates of Auspicious Passage, allowing one to cross vast distances with a single step (although only to a similar Gate). They require truly monstrous amounts of power to function even for brief periods however, and are extraordinarily difficult to build, repair and program.
* Similar to the ''Call of Cthulhu'' example, ''TabletopGame/ArkhamHorror'' has gates to other universes that the players must close in order to win.

[[folder:Theme Parks]]
* ''Theatre/PoseidonsFury'' at [[Ride/UniversalStudios Universal's Islands of Adventure]] has guests pass through a "water vortex" (a huge tunnel with flowing water surrounding it) in order to get to the room where the attraction's finale takes place.

* ''VideoGame/DistortedTravesty 3'' gives us big swirly holes with [[https://youtu.be/cN7eE3pNzAs?t=5s blue (or red, in the case of nightmare gates)]] lightning scything out of it.
* ''VideoGame/AgeOfMythology'' has a whole bundle of them—the adamantine, gods-can't-break-'em Gates of Tartarus alone are worthy of mention. There's also:
** The gates of Troy (duh), which are as close to magically-indestructible as mortals can get.
*** The even more almost-indestructible Atlantean Gate, made of [[GreenRocks green granite]] or something.
** The cavernous Underworld Passage that Apollo allows you to summon in-game
** The strip-mined entrance to Erebus constructed by Gargarensis in Iolchis
** The folding staircase over nothingness leading ''out'' of Erebus that [[DeusExMachina Zeus summons to save Arkantos]]
** The Well of Urd, also an entrance to Erebus
** The Sky Passages that Oranos uses to get his followers from place to place
** The hellhound-sized Tartarus entrance that Hekate summons to release her little minions—shaped like a skull
** And the various entryways the Titans use when you summon them. Cerberus, Ymir, and the Atlantean rock-thing (Typhon) all have big pit/mound shafts that collapse behind them, but Horus requires you to build him a ''god-sized landing platform'', appropriately decorated, of course.
* ''VideoGame/ChronoTrigger'''s aptly-named Gates.
* ''VideoGame/CityOfHeroes'', being ''filled'' with superhero tropes, has a generous number of these- from Portal Corps' eponymous portals (which are huge, glowing, have moving bits, and are bloody ''loud'') to the fairy ring portals into the spirit world, to the annoyingly random portals throughout the mystic lost city of Oranbega. It's got something for everyone.
* The Oblivion Gates from ''VideoGame/TheElderScrollsIVOblivion'', which let Daedra out of the gate's titular dimension. Note that they are shaped like the rune on the box art, which is the letter "O" in Daedric.
* All of the major powers in ''VideoGame/EveOnline'' have their distinct stargate designs to facilitate interstellar travel.
** Coolest are the massive border stargates over 20 km across setup at the boundaries of each empire.
*** Not to mention the EVE Gate itself.
* If it's in anyway [[{{Precursors}} made from the Zilart race]], places in ''VideoGame/FinalFantasyXI'' feature tons of portals, gates, and what have you. Several other portals and gates also qualify.
** Some examples. Many of them have special items that allow you to open them like normal doors, but you generally have to be able to get behind the door first:
*** The "Moongate", which only opens for a very short period of time in the rather lengthy in-game moon phases.
*** A certain door only opens when you have a White Mage, a Red Mage, and a Black Mage stand on their respective panels
*** One dungeon has doors which require a certain amount of 'weight' to be placed on sensors (determined by the amount of player characters, and what race they belong to)
* ''Franchise/{{Disgaea}}'s'' dimensional gate warps the user to the selected location.
* In ''VideoGame/GhostHunter'', a painting in a mansion becomes a doorway. On the other side the portal is a plain doorway standing in the open, through which the interior of the mansion can be seen.
* Mailboxes in ''VideoGame/GliderPRO'' have instantaneous delivery. It's also common to place teleporters in mirrors and paintings of Ozma.
* ''Franchise/KingdomHearts'' has lots of them. Most notably the door to the titular heart of all worlds. It's a game in which the main character wields [[ImprobableWeaponUser a gigantic key]]. Doors tend to be prominent.
* Interstellar gates are a possible technology in the first two ''VideoGame/MasterOfOrion'' games.
* The gates between Dark and Light Aether in ''VideoGame/MetroidPrime2Echoes''.
* The protagonist's wand is seen to produce a ''very'' cool one in the trailer for ''VideoGame/{{Ninokuni}}''. Presumably it takes him to the titular Another World.
* The Spirit Gate in ''VideoGame/{{Okami}}''. [[spoiler:It takes the player 100 years into the past.]] The Golden Gates also serve as checkpoints, and Devil Gates lead to a battlefield with more enemies than usual for the area.
* The Flower Gate in ''VideoGame/PaperMario'''s Toad Town led to Flower Fields—but only when the four Bub-ulb seeds had been planted in the garden.
** The titular gate in ''VideoGame/PaperMarioTheThousandYearDoor''.
* ''VideoGame/{{Portal}}''. Apart from the titular portals, there is the "Aperture Science Material Emancipation Grill." In order to prevent you from carting useful (and possibly game-breaking) objects into other levels or putting portals across levels, each level end is blocked by a shimmering particle field that dissolves unauthorized objects as they pass through it, and closes all portals. It may, in semi-rare cases, emancipate dental fillings, crowns, tooth enamel, and teeth, as well as ear tubes. It is especially gratifying to drag the robot turrets through it.
--> '''Robot turret''': Ow! Ow! Ow!
* Rift Gates in ''VideoGame/{{Primal}}''.
* Comically averted in the 7th installment of the ''VideoGame/{{Touhou}}'' series (''Perfect Cherry Blossom''): at the end of the 4th stage, the playable character [[CuteWitch Marisa Kirisame]] comes across a giant gate at the entrance to the Netherworld; she notices that the gate is magically sealed, and states that a novice magician such as herself wouldn't be able to open it. Then, she is greeted by three ghost musician sisters, and finds out that they were invited for a celebratory musical performance into the Netherworld and are able to enter and leave it at will. [[spoiler: Marisa then demands that they open the gate for her, and the three of them fight her. After the ghost musicians are defeated, Marisa tells them to open the gate, and the ghosts say that the gate won't open. Marisa then asks how they enter and leave the Netherworld at will, only to hear that they fly above it.]]
* ''VideoGame/{{Turok}}''[='s=] ever present Warp Portals.
* The [[spoiler: Vanishing Point]] in ''VideoGame/ShinMegamiTenseiStrangeJourney''.
* The ''VideoGame/{{Ultima}}'' series had Moongates, which got cooler and cooler each game up to the 9th. Drop a pebble in a ring of standing stones, and with a clap of thunder a bright, shimmering indigo gate springs from the ground.
** Initially Time Gates (in Ultima ][, directly inspired by ''TimeBandits''), they quickly became associated with the phases of the moon, and then got increasingly complicated as blue, red, and black moongates were introduced.
* The Dark Portal from ''VideoGame/{{Warcraft}}'', particularly on the [[http://www.wowwiki.com/File:Darkportal-outlandside.jpg Outland]] side.
** The warlock class can create demonic gates through which other party members can be summoned to the gate's location.
** The mage class can create temporary portals to their respective side's capital cities, as well as the neutral cities added with the expansion packs.
** The Death Knight class can create a Death Gate, the purpose of which is to allow easy access to trainers.
** There are also the portals to the Emerald Dream. Four portals in forested areas around Azeroth, guarded by hostile dragons. The other side is not accessible in-game, but according to the lore it leads to another dimension that is what Azeroth would be without intelligent humanoid life of any kind, populated by myriad magical beasts.
** The Burning Legion actually needs to make huge and powerful magical portals to send their strongest to Azeroth.
* The original ''VideoGame/{{Doom}}'' has the Phobos and Deimos anomalies, two ancient, connected portals discovered on each of the Martian moons. Unfortunately for the researches studying the anomalies, they work by teleporting matter [[HyperspaceIsAScaryPlace straight through Hell]]. When an experiment goes out of control, Deimos is pulled completely through its anomaly and ends up drifting above Hell, forcing the SpaceMarine to use the Phobos Anomaly to reach it. The anomalies also serve as the basis of the in-game teleporters, which work like a PortalNetwork and, if the player's not careful, can lead to the trope-naming TeleFrag.
** The ContinuityReboot sequel ''Doom 3'' changes the story to remove Phobos and Deimos. Instead, the portals that cause all the current trouble were built by the UAC colonists and based on the Martian civilization's ancient schematics (the schematics were actually meant as a warning, but the scientists missed the fine print). The original ancient portal that [[IncrediblyLamePun doomed]] the Martians does become a plot point late in the game as, once the human portals have been shut down and the DemonicInvaders seemingly stopped, they blast open the original Martian portal instead.
* It's a fairly big plot point that the [[spoiler:Citadel]] in ''Franchise/MassEffect'' is one of these, linking the known galaxy to wherever the [[EldritchAbomination Reapers]] are.
* As mentioned in the Tabletop [=RPG=]s section above, ''VideoGame/PlanescapeTorment'' has a ton of these. It's part of the setting, after all.
** Not just for transport, too: They provide [[http://www.youtube.com/watch?v=OKZZEPoVb4c a handy solution]] if your {{BFG}} is too big to carry.
* ''VideoGame/{{Achron}}'''s teleporters and chronoporters (that facilitate mass teleportation and mass time travel respectively) look like cool spinning stargates. Which is a bit [[RuleOfCool unnecessary]] since no unit actually ''walks'' through them.
* Egosoft's VideoGame/{{X}}-Universe series has both Jump Gates, [[PortalNetwork linking sectors of space]], (which may or may not be neighboring in actual space, or millions of light years apart.), while the Terran race has two Jumpgates for Earth, and a network of Trans-Orbital Accelerators, which are basically starship railguns, flinging ships across the Sol system, though they cannot be targeted by the jumpdrive.
** ''Videogame/XRebirth'' retains the Jump Gates, and adds in massive Super Highway gates, which create streams of energy capable of accelerating ships to faster-than-light speeds for interplanetary travel, and smaller highways for travel within planetary orbit.
* Far Gate's wormholes. Basically a combination of this and SwirlyEnergyThingy with DNA-shaped pink and blue strands coming out from the middle.
* ''VideoGame/TheCrystalKey'' uses simple arches activated by the titular key to provide direct transport between the Arkonian colony planets. The number of places you can go is determined by the number of "planes" attached to the key. They recently perfected the ability to design portable portals as well, from small remote-controlled ones you can carry around - and which go with you when used, to huge rods mounted on spaceships, which they used to deter the [[DarthVaderClone malevolent psychic warlord, Ozgar.]]
* In ''VideoGame/{{Minecraft}}'' is possible to build nether portals with obsidian, obsidian being the most time consuming resource to acquire.
** As of Beta 1.9Pre4, End Portals are also available. These are even more difficult to find since they are only found in strongholds and only 128 of those spawn on the entire map. Also, the Enderdragon is on the other side of End portal.
*** As of 1.9, after you kill the Enderdragon, yet another Cool Gate spawns in the sky. There is no way to enter it without using an ender pearl, and if you do enter it, you are taken about a kilometre away from the central FloatingContinent in the End, where you find endless seas of islands with purple trees and strange castles, sometimes with a CoolAirship docked at them.
* Inverted in ''VideoGame/GalacticCivilizations''. Star Gates were once used for interstellar travel, but they suppressed exploration of other parts of the galaxy because they could only move ships between any two of them, plus it took quite a while for them to transport ships. The rise of Humanity gave rise to Hyper Drive, which allowed ships to travel great distances on their own, rendering the Star Gates obsolete and setting the stage for the game's plot.
* The Gate of Time in ''VideoGame/TheLegendOfZeldaSkywardSword''.
** The very similar-looking Gate to the Twilight Realm in ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'', as well as the door to the past in the Temple of Time.
* ''[[VideoGame/EscapeVelocity EV Nova]]'' has a network of LostTechnology hypergates that serve as a WarpWhistle of sorts. Once you get a license to use them via the [[MegaCorp Sigma Shipyards]] questline, they allow you to travel between certain star systems instantaneously, whereas using your hyperdrive causes the InUniverseGameClock to increment between 1 and 3 days depending on your ship's mass. A smart player will memorize the hypergate network, as it's sometimes the only way to get rush jobs done by the deadline.
* ''VideoGame/EarthAndBeyond'' had a few varieties of gates. [[{{Precursors}} Ancient]] [[LostTechnology Gates]], which according to some in-game material may have been sentient, and could send a ship as far as 100,000 light years. Reverse engineered [=InfinityGates=], far less powerful with only a few light year range. And the singular Tada-O Gate, also reverse engineered from the Ancient Gates, but thought to connect to another galaxy... [[AlienInvasion oops]].
* In ''VideoGame/CivilizationBeyondEarth'', the victory conditions for the [[NoTranshumanismAllowed Purity]] and [[{{Cyborg}} Supremacy]] affinities involves building the Exodus and Emancipation Gate, respectively. They are so huge that they require a whole game cell to build. They look pretty much identical, except the Exodus Gate generates a red portal in which the energy appears to flow outward, while the Emancipation Gate flows inward and glows yellow. The former is used to bring in refugees from the building faction's territory on Earth to settle on the new world. The latter is used to send troops back to Earth to undergo UnwillingRoboticisation.
* ''VideoGame/NoMansSky'' has these at mysterious alien temples, which can take players who find them across the universe almost instantaneously (after briefly covering them in a liquid-like substance)... Without their ship, of course; but there's no such thing as a free lunch.
* One of the ways to get to new locations in ''Videogame/WitchesLegacy''. They are often both ways, sometimes they lead to some form of EldritchLocation and other times just somewhere new.
* The conspiracies' agents in ''VideoGame/TheSecretWorld'' travel using Agartha, a network of portals in and around the branches of enormous biomechanical trees located in [[HollowWorld the Hollow Earth]]. (It's that kind of game.) Only a handful of others can use Agartha without ... [[GoMadFromTheRevelation consequences]].
* The [[RealityWarper Conduit]] from ''[[NexusWar Nexus Clash]]'' has the power to create wormhole gates between two points, no matter how distant. Wormholes are stable enough to march an army through - which is usually exactly what Conduits want them for.

[[folder: Web Comics ]]
* In ''Webcomic/NoRestForTheWicked'', it's surrounded by CreepyCrows, [[http://www.forthewicked.net/archive/04-10.html it has to be dug up]], it's [[http://www.forthewicked.net/archive/04-47.html an ordinary door—flat in the ground]]; and [[http://www.forthewicked.net/archive/04-49.html when they open it]], [[http://www.forthewicked.net/archive/04-50.html it draws November and Clare in]].
* The five Gates in ''Webcomic/TheOrderOfTheStick'', though you're [[ContainmentField not meant to walk through them]] -- they're built on [[spoiler:holes in the fabric of the universe leading to a demiplane containing an EldritchAbomination.]]
** [[RunningGag What gates?]]
* In ''Webcomic/DreamCatcher'' due to running in between the two worlds, Riza gets plenty of use out of a couple. One being a door, the other being the titular dreamcatcher.
* In the comic WebComic/{{Flipside}}, creating a portal involves slapping a door-sized piece of enchanted paper on a surface.
* ''Webcomic/{{Thunderstruck}}'''s take on [[http://talesfromthevault.com/thunderstruck/comic427.html magical portals]].
* In ''Webcomic/PlanesOfEldlor'', the dragons are concerned about the appearance of a strange vertical rift which turns out to be the precursor of a gate to the demonic realm.
* ''Webcomic/BobAndGeorge'': [[http://www.bobandgeorge.com/archives/001228 The portal]]
* The portal cloth of ''Webcomic/WapsiSquare'' is interesting [[http://wapsisquare.com/comic/youllberightback/ on its own,]] but it really becomes a cool gate when it is [[http://wapsisquare.com/comic/atattoo/ attached to Shelly.]] If you enter it, you come out the other cloth, but you have to be able to teleport on your own to use it. It still does have its uses though.
* ''Webcomic/{{Underling}}'': Portal travel is common. [[http://underlingcomic.com/page-one-hundred-fifteen/ Like this one.]]
* ''Webcomic/ProblemSleuth'': Almost anything can be a gate: windows, traffic lights, hot tubs, corsets... it's a weird story. Also there is the door to Death.
* ''Webcomic/{{Homestuck}}'' Each game planet has seven gates, which teleport players to far-off regions of their planets and to other players' planets. There are also return nodes which, predicably, return the player to their house. Finally, there are defence portals used by Skaia to teleport approaching meteors away to the players planet (most of them land [[TimeTravel before the players start playing]]).
* In ''Webcomic/{{Endstone}}'', the Eternity Spire [[http://endstone.net/2011/02/14/5-09/ let you create them.]]

[[folder:Web Original]]
* ''Literature/AssociatedSpace'' uses Catapult Points for interstellar travel. These are giant metal circles placed in orbit around a sun, which gives the devices the immense amount of power necessary to use the things. Once a ship goes into the circle, the gate activates, creating an effect that zaps the ship to another star system, which catches you with similar catapult point, using its immense power to disrupt the effect.
** How does the effect work? Very well, thank you.
* The Einstein-Rosen bridge from ''Roleplay/DarwinsSoldiers''.
* ''TabletopGame/TechInfantry'' has several types.
** Jump Gates, immobile spaceborne structures that open up a portal to Hyperspace for ships that can't open up a jump point on their own.
** Digital Gates, immobile spaceborne structures that scan an entering ship, convert it to pure energy, and beam that energy in the form of tachyons, to another digital gate in a distant star system, which re-converts the ship back into matter at the other end, for near-instantaneous interstellar travel.
** Correspondence Portals, which certain Mages can create as a sort of magical emergency point-to-point teleportation system.
** Transit Beacons, a [[{{Magitek}} weaponized]] military version of the Correspondence Portal, built into a starship, and used to teleport whole formations of soldiers at once down to the surface of a hostile planet.

[[folder:Western Animation]]
* The ''WesternAnimation/WheresWaldo'' cartoon (possibly a video-only series) utilized Waldo's "hiding" aspect by making his cane magical—he traced a ring with its tip in the air in front of him to create a portal to anywhere. It was his EvilTwin [[SdrawkcabName Odlaw's]] desire to steal this cane and use it for nefarious purposes.
* In the ''Comicbook/DoctorStrange'' animated movie, the Sanctum Sanctorum contained a gate to Dormammu's realm.
* ''WesternAnimation/FamilyGuy'''s ''Film/{{Poltergeist}}'' parody has ''Meg's butt'' as one end of a portal.
* ''WesternAnimation/ReBoot'' copied the Franchise/{{Stargate|Verse}} in one episode and [[CallBack brought it back]] in a later episode. The show also had sphere portals, which functioned in a similar manner.
* In ''WesternAnimation/TransformersPrime'' the [=GroundBridge=] and its big brother [=SpaceBridges=] function as long-distance (in the latter case, at ''least'' interplanetary) transport gates, with the space "in between" being [[OurWormholesAreDifferent spacious enough to fight in]].
** The Space Bridge has been seen in many Transformers series - never the same in any two versions, but pretty darned cool in all of them! Depending on the version, sometimes you only need a device on the "sending" end and can target it anywhere, but sometimes you need a device at both ends. There are also versions where they're part of a PortalNetwork similar to the StargateVerse's gates, only visible when in use and no hardware ever seen; sometimes bots seem to summon portals out of nowhere but are unable to do it to a place that 'doesn't have a space bridge.'
* The portal in ''WesternAnimation/GravityFalls'' that [[spoiler:Stanford Pines]] built and fell in.
* In ''WesternAnimation/LegionOfSuperHeroes,'' we once see a PortalNetwork's [[PortalCrossroadWorld hub]], with some very StargateVerse-esque gates.

[[folder:Real Life]]
* Well, real theory: [[http://en.wikipedia.org/wiki/Wormhole Wormholes]], [[http://www.geeknews.net/2008/08/14/physicists-spooked-by-faster-than-light-data-transfer this]].
