->''You know, [[RememberWhenYouBlewUpASun you blow up]] '''[[RememberWhenYouBlewUpASun one]]''' [[RememberWhenYouBlewUpASun sun]] and suddenly everyone expects you to walk on water.'' \\
-- Samantha Carter

Popular ScienceFiction series (1997-2007) following on from ''{{Stargate}}'' the movie (in a BroadStrokes fashion), following the adventures of the US Air Force's SG-1 team as they travel through a [[FasterThanLightTravel wormhole]] to planets called P3-something or other. Started out as more light-hearted [[{{Nineties Adventure Show}} Nineties Adventure fare]], gradually [[{{Cerebus Syndrome}} grew more heavy and serious as its mythology progressed]]. {{YMMV}} as to which was better.

Lasting for 10 seasons, it was the second longest running Sci-Fi show in US history. However, the show was not renewed for an 11th season. Two DVD movies have so far been made, ''[[TheArkOfTruth Stargate: The Ark Of Truth]]'' and ''[[StargateContinuum Stargate: Continuum]]''; the third and final SG-1 movie, ''Stargate: Revolution'', is currently being filmed.

It should be noted that as they are simply modern day Americans, ''Stargate'''s earthling characters rarely suffer from GenreBlindness (although the aliens on the show certainly do, leading the audience to believe that soaking up enough pop-culture means that IKnowMortalKombat). The main characters are very aware of the trappings of science fiction, and not afraid to show it. For instance, they suggested calling Earth's first FTL ship the "Enterprise".

Spinoffs: ''StargateAtlantis'', the animated [[CanonDisContinuity non-canon]] ''StargateInfinity'' (see FiveManBand), ''StargateUniverse''.

->''These and other cliches will be available to you all for one more day of training with me. After that, you'll either be assigned to an SG team... or not.'' \\
-- Jack O'Neill (''Proving Ground'')

This show provides examples of:
* AbusivePrecursors: The Ori are outright evil.
* ActingForTwo: "Tin Man", "Point Of View", "Double Jeopardy", "Ripple Effect" & any episode with Ba'al and his clones.
* AdventureTowns: Technically, adventure [[{{Planetville}} planets]], but the effect's the same...
* AffablyEvil: Ba'al
* AliensSpeakingEnglish: Despite Dr. Jackson in the original movie having to translate the naturally-evolved ancient Egyptian ''spoken by humans'', and thrown out the window as the plot required.
** It cannot be over-emphasized how jarring this was in the early seasons. SG-1 clearly still expects incomprehensible languages- Jackson is consistently asked to work his magic before the locals surprise everyone by speaking up in English. Yet they ''never question it''. Later seasons wisely [[BellisariosMaxim call less attention to the whole thing.]]
**This troper thinks that the Ancients had something to do with this, as Ancient evolved into Latin and Latin into English and so on. They DID have almost complete influence over both the Milky Way and Pegasus galaxies, after all.
*** Makes little sense as even Earth has managed to "evolve" dozens of languages from a Latin root.
**** Do people speak something else than English in the series? Maybe in their universe everyone on earth speaks English. I haven't seen all the episodes, but all episodes I did see had either alien languages, english or aliens speaking English.
* AllYourBaseAreBelongToUs: Various foothold situations.
* AlmostLethalWeapons: Zats, etc.
** And, ironically, the BigBad's main weapon.
* AlternateUniverse: Loads and loads of them. For extra fun, a bunch end up converging on the gate, and two dozen Sam Carters are left working together to figure out a solution.
* AncientAstronauts: Pretty much every ancient culture ''ever''.
* ArmorIsUseless: For the Goa'uld and Jaffa
* AscendToAHigherPlaneOfExistence: TropeCodifier
* {{Badass}}: Teal'c can knock a man out with an ''avocado'' at 100 yards.
** BadassCrew: SG-1. Several enemies wanted to destroy the Earth, just to ensure that those four would be dead.
* BackedByThePentagon: Specifically the US Air Force.
* BaldOfAwesome: Teal'c before season 8; General Hammond.
* BewareTheNiceOnes: Reese is an absolutely adorable little android girl who just wants to be friends with you and to play with her toys. ''Do not anger her.'' If you're lucky, she'll just throw you through a wall. If you you're not, [[spoiler:well, her "toys" happen to be Replicators, and they will annihilate all human life on the planet if she feels threatened.]]
* {{Big Bad}}s: First ThePuppetMasters, the Goa'uld, especially Apophis. Then the AIIsACrapshoot Replicators. Then evil Goa'uld turned [[EnergyBeings energy being]] Anubis. Finally, a whole RACE of evil EnergyBeings called the Ori, and their DarkMessiah Adria. Honorable mention goes out to Ba'al, TheStarscream, who played secondary villain to most of the above, and managed to outlast them all.
* BigDamnVillains: Sort of. [[spoiler:The Replicators kill off most of the Goa'uld at the end of Season 8--fitting the trope--but on the other hand the only thing preventing SG-1 & Co. from doing that themselves was practicality, not morality--which is not in the spirit of the trope.]]
* BlackSpeech: The language of the Goa'uld.
* BluntMetaphorsTrauma: Teal'c and Vala
* BoardToDeath: Ba'al to all his clones. [[supersecretspoiler:At least most of them.]]
* BoomStick: Teal'c and the Jaffa's signature weapon. Later also used by the Ori Soldiers.
* {{Brainwashed}}: Several times.
* TheBusCameBack: Jonas in "Fallout"
* ByTheEyesOfTheBlind
* CaliforniaDoubling: Canadian variant
* CannotTellAJoke: Teal'c
* CargoCult: More or less the basic premise of the show.
* {{Catchphrase}}: ''Indeed''
** Ya think?
** Ah, fer cryin' out loud!
** Jaffa, kree!
** Yeah, I get that a lot.
** That's what I'm talking about!
** Lunch?
**Chevron seven locked.
* CharacterizationMarchesOn: When he's introduced in "Summit," Ba'al is described as a ruthless, sore loser that once wiped out two star systems rather than lose them to Cronus. A little different from the AffablyEvil MagnificentBastard of the last couple seasons.
** This could be just an example of {{Character Development}} rather than {{Continuity Drift}}. When he was introduced, the Goa'uld were still complacent about and dismissive of Earth humans, and so far they had only targeted his enemies. By the end of the series, Ba'al had been forced to serve under a half-{{Energy Being}} Goa'uld, the Goa'uld hegemony of the galaxy had been destroyed in large part thanks to the SGC, and he had started cloning himself to have proxies and decoys. All those experiences could teach anyone some humility, respect for one's adversaries and flexibility, even a Goa'uld.
* ChekhovsArmoury: Everyone they meet. Everything they find. Everything they bring back. Everything they do to their Stargate [[strike:beyond simple dialling]]. Even the EngagingChevrons is a plot point in some episodes (''because'' it's so slow.)
* ChickMagnet: It seems that every other female character will try to get into Daniel's pants at some point. Marginal example because Daniel often gives in. Lampshaded in an early episode when O'Neill says at this rate, he's going to have a girl on every planet.
* [[{{ptitletnnwhqnhdt9x}} Clarke's Third Law]]
* ClipShow: Also parodied in "200".
* CloneDegeneration
* CloseEnoughTimeline
* ColonelBadass: Now, who might it be?... [[spoiler:[[CompletelyMissingThePoint Carter]]]]? [[spoiler:[[CompletelyMissingThePoint Mitchell]]]]?
* CommutingOnABus: O'Neill was promoted to General so his onscreen time could be significantly reduced, reflecting Richard Dean Anderson's desire to spend more time with his family.
* CompleteMonster: Anubis
* ConspiracyTheorist: Martin Lloyd in the episode "Point of No Return".
* CoolGate: Duh!
* CoolOldGuy: Hammond, Landry, Bra'tac and Jacob Carter.
* CopBoyfriend: For Sam. [[spoiler: It doesn't last.]]
* CosmopolitanCouncil: The Goa'uld, surprisingly. Doesn't make them any less evil though.
* CrowningMomentOfAwesome: '''Every''' single main character gets at least one of these at one point or another, even Hammond. And sometimes even single-appearance characters get one.
** Even ''[[EngagingChevrons Chevron Guy]] Walter'' gets one in an ExpandedUniverse BigFinish audio drama, where he single-handedly stops an enemy menace from destroying the Stargate at great personal risk to his own life. After this entire adventure? He responds with...
---->''I'm no hero. I just press buttons. I'm just... the [[EngagingChevrons Chevron Guy]].''
* CrowningMomentOfFunny: "Window of Opportunity," specifically the "This is a time loop so you can get away with anything" montage. Also, Daniel Jackson in the episode ''"The Sentinel"''.
-->'''Lieutenant Kershaw:''' I feel better just knowing there's an archaeologist watching our backs.
-->'''Dr. Daniel Jackson:''' (holds up a knife) Yeah, which end do the bullets go in again?
* CunningLinguist: Daniel Jackson
* DaydreamSurprise: In the episode "Grace".
* DeadpanSnarker: Jack O'Neill, with Daniel Jackson occasionally getting into the act; the latter mentions, after annoying a Russian officer, that he's been spending too much time with Jack. People meeting Jack for the first time will sometimes [[LampshadeHanging ask the question, "Is he always like this?"]]
-->'''Ba'al:''' You dare mock me?
-->'''O'Neill:''' Ba'al, come on, you should know me by now. Of ''course'' I dare mock you.
* DeathByPragmatism: On occasion.
* DeathIsCheap: But only if your name is Daniel Jackson, who dies between 6 and 22 times over the course of the show, depending on whether you count [[{{Left For Dead}} presumed deaths]], [[{{Alternate Reality}} alternate realities/timelines]], AllJustADream episodes, [[BigFinish expanded universe audio dramas]], etc.
** And, for someone else, in the episode Abyss [[spoiler:Jack is killed several times & brought back by Ba'al]]
** Everyone of the original SG-1 team dies at least once. [[spoiler:in the episode where they meet the Nox, killed by Apophis]]
** This eventually happens to Daniel so often that it becomes one of the series' {{Running Gag}}s. Consider this scene where two {{Mauve Shirt}}s are exploring an archeological site on another planet:
---> "Dr. Jackson's going to die when he sees this!"
---> "Again?"
*** So much so that it's a little surprising it wasn't at least acknowledged in "Ripple Effect." Like having an alternate SG-1 come through sans Jackson, followed by something like, "Where's Jackson?" "He got killed." "Of course he did."
** BigFinish's first audio drama for the Stargate-verse? [[spoiler:Killing off season 3 Daniel Jackson and making ''an exact duplicate of him'' his own JonasQuinn]]. [[SoYeah Yeah]].
* DeliveryGuy: Daniel Jackson, [[spoiler: right after finding Sha're again, Goa'uld-infested and heavily pregnant with Apophis' child]], and to a woman giving birth alone in a temple.
* DescriptionCut: In "Cure", regarding O'Neill.
* DestructiveSaviour: The Tok'ra see the Tau'ri this way.
* DidNotDoTheResearch: Mostly averted, but a couple episodes are particularly [[TVTropesWikiDrinkingGame egregious]], especially the Mongols in "Emancipation".
** Being radically different from the originals was a major plot point. The fact that any of the cultures they meet are recognizable AT ALL is much more egregious in terms of Anthropology, given the millennia that have supposedly passed.
*** The above statement was referring to Daniel's highly erroneous statements in that episode, not the actual depiction.
* DirectedByCastMember: Amanda Tapping, Michael Shanks, and Christopher Judge all wrote or directed episodes.
* DressCodedForYourConvenience
* DudeNotFunny: YOU try laughing at the episodes with Martin when you have a paranoid schizophrenic relative who goes on about everything from black helicopters to shadowy government figures planting bombs in her yard. Just try it.
** Still funny to the majority of people who don't have brushes with such people in RealLife.
* EvilIsSexy: Most of the Goa'uld, especially the female ones. There's also Adria of the Ori, played by Morena [[{{Firefly}} "sponge bath"]] Baccarin.
** Justified in the former case because Goa'uld seek out the most healthy and beautiful of humans to serve as their hosts and justified in the latter case by the fact that Adria inherits her hotness from her mother Vala.
* EngagingChevrons: TropeNamer
* EvilHasABadSenseOfHumor: Naturally, the GenreSavvy O'Neill doesn't trust anybody who appears to lack a sense of humour.
* EvilTwin
* EyeOpen
* FacialMarkings: Jaffa
* FakeAmerican: Amanda Tapping was born in England and has spent most of her life in Canada.
** Michael Shanks is from Canada. Gary Jones (Walter "The Chevron Guy") was born in Wales, but now lives in Canada. Most of the guest actors are from Canada. They corrected this (sort of) in ''StargateAtlantis'' by having Dr. Rodney [=McKay=], who's from Canada, played by David Hewlett who's ''actually from Canada''.
* FakeNationality: Perhaps most notably, English actors Gary Chalk and Marina Sirtis play Russians.
* FakeRussian: With BilingualBonus and shades of NoFourthWall at times if you can handle the bad grammar.
* FeedTheMole
* FetishFuel: [[{{FetishFuel/StargateSG-1}} Has its own page.]]
* FiveManBand: Only really prevelant in later seasons.
** Colonel Mitchell is TheHero.
** Samantha Carter is TheLancer.
** Teal'c is TheBigGuy
** Daniel Jackson, TheSmartGuy
** and Vala Mal'Doran, the Chick and possibly SixthRanger.
* FloatingContinent: Floating city, really.
* ForgottenPhlebotinum: Since a major part of SG-1's mission statement is to find useful technology, this is averted a lot. But it inevitably happens even more.
* GenreSavvy: Pretty much the whole team, but O'Neill and Mitchell stand out.
* GhostCity: In "Bain", "Ascension", "2001", and "Menace".
* GirlishPigtails: Subverted by Vala.
* GodEmperor: Standard Goa'uld PR theme.
* GodsNeedPrayerBadly: How the Ori get their power.
* GoshDangItToHeck: When particularly annoyed, Mitchell will exclaim "Mary and Joseph!" Given his delivery, he may as well have left the first name in.
* GovernmentConspiracy
* GreenEggs: Played straight in season 4's "Beneath the Surface;" lampshaded the following season, in "Wormhole X-Treme!"
* GroundhogDayLoop: The mostly-comedic "Window of Opportunity" episode, a fan favorite.
* GunsAkimbo: Teal'c silently trades his standard staff weapon for dual P-90s between the 8th and 9th seasons [[spoiler:likely to commemorate his people's freedom]].
* HeroOfAnotherStory: Colonel Makepeace; later Colonel Reynolds when Makepeace is [[spoiler:revealed to be TheMole]].
* HeyItsThatGuy: As location shoots were mostly done in Vancouver, there is the occasional appearance of someone from the new BattlestarGalactica. Also, ''{{MacGyver}}''. Having nothing to do with Vancouver, several StarTrek actors made guest appearances. And Seasons 9 and 10 turned into 'cancelled show central', with actors from ''{{Farscape}}, {{Andromeda}}'' and ''{{Firefly}}'' turning up, mainly as {{Jonas Quinn}}s.
** And as a smaller tidbit, Jay Felger is [[TheRedGreenShow Harold]].
* HideYourPregnancy: Four times, three actresses. Amanda Tapping was in the last months of her pregnancy when filming began for Season 9, leading to Carter being temporarily assigned to Area 51. Lexa Doig became pregant with her and husband Michael Shanks' second child during filming for Season 10, resulting in her character of Dr. Carolyn Lam having a greatly reduced prescence and all but disappearing from the show. Claudia Black was also pregnant with her first child in Season 9, resulting in her character Vala Mal Doran being [[spoiler: trapped in the Ori galaxy for much of the year]] before her return in the last two episodes of the season. When filming began for the SG-1 movie ''Continuum'', Black was again pregnant, but since the role of [[spoiler: Qetesh]] was an important part of the story, Black wore a loose-fitting dress and was filmed from angles that would minimize her stomach, as well as having obstructions placed in the camera's line of sight. Inverted in the second season episode "Secrets", when the actress playing Sha're (Vaitiare Bandera) [[RealLifeWritesThePlot was actually very pregnant]] with her then-partner [[ReallyGetsAround Michael Shanks]]' child.
* HolodeckMalfunction: The episode "Avatar".
* HollywoodNerd: Sam and Daniel
* HotScientist: Sam Carter
* HowManyTimesMustIKillYou: Apophis and Ba'al are this trope given physical form, though Ba'al kind of has an excuse. Anubis is this trope given noncorporeal form.
* HoYay: Sort of hinted at with Jack & Daniel, although you almost have to ''want'' to see it. Further explored in the world of {{Fanfic}}. Lampshaded in the 200th episode.
* HufflepuffHouse: The Tollan, and to a lesser extent the Tok'Ra, who in millennia haven't earned nearly as many victories as the Tau'ri in a scant 10.
** Of course, the Tok'Ra, being Goa'uld, have the life spans for it. Also, they were trying to set it up so that they could take out ''all'' of the system lords at once. On at least two seperate occasions, two different Tok'Ra(Jacob/Selmak and Dellek) point out that their lack of showy victories is on purpose -- the humans' tendency to find the biggest bad guy they can and kill him often makes the situation ''worse'', by consolidating power in the hands of a few tyrants rather than having it split among many fractionated, squabbling system lords.
** Given the total lack of *any* progress towards their end by the Tok'ra this troper is less than impressed by their reasoning.
*** Even more true now that going by canon the Tau'ri have totally shattered the System lords, been the driving force in defeating a race of super adaptive machines threatening two galaxies, killed off a race of super powered religious fanatics dozens of ''eons'' old, and appear well on there way to purging a fourth hostile alien race that defeated the much lauded Ancients. They did all this in about a decade with a tenth the starting technology of the Tok'ra and come out stronger for it. In fact now being probably more powerful then the Tok'ra ''ever'' were. Hufflepuff indeed.
**** However, it's arguable that without the millenia of Tok'ra fighting the Goa'uld, they would have been so strong as to be impossible to defeat by the time the Tau'ri went through the Stargate.
* HumanAliens: Mostly Justified as TransplantedHumans, but the Ancients' deal was never really clarified
** The Ancients actually ARE the ancestors of the human race, without THEM we would look otherwise.
* HumansByAnyOtherName: "Tau'ri", meaning "those from the first world." Admittedly more original than most other examples.
* HurricaneOfPuns: When Ba'al begins cloning himself, Ba'al-related puns become quite common.
* HypocriticalHumor: In "Disclosure", the ''Chinese ambassador'' actually manages to say the phrase, "The Chinese government does not believe in keeping secrets from its people" with a completely straight face, which is a bit like hearing Josef Stalin declare that killing people is wrong.
* ICanSeeMyHouseFromHere
* IComeInPeace:
-->'''Jack O'Neill:''' "We come in peace. We hope to leave in one... piece".
* [=~I'll Take Two Beers Too~=] (when the team is under the influence of appetite-increasing phlebotinum)
* [[IdiotBall Idiot]] [[IncrediblyLamePun Ba'al]] (Pretty much everyone holds it at some point. Specifically, any Goa'uld (villain or not), any planet visited by a Prior of the Ori, and SG-1 from time to time.)
* ImperialStormtrooperMarksmanshipAcademy: The Jaffa, although justified in later episodes when Jack explains that the staff weapons are designed to intimidate, while human weapons are designed to kill.
** The quote is just too epic to pass up:
--> Col. O'Neill: {Hefts a Staff weapon} "This is a weapon of terror. It's made to intimidate the enemy." {Returns Staff to owner, hefts P90} "''This'' is a weapon of ''war''. It's made to ''kill'' your enemy."
* ImplacableMan
* InHarmsWay: Carter is a real adrenaline junkie in her spare time.
* InstantAwesomeJustAddDragons: One of Merlin's tests.
* JacobMarleyWarning: Ernest to Daniel in "The Torment of Tantalus".
* TheJohnHenry: Stargate SG-1's humans, who firmly believe that good old-fashioned Earth bullets work better than Goa'uld weapons. They get their chance to prove it once the Replicators enter the scene. That and guns are easier to shoot than a staff weapon.
** It's really the Goa'uld's fault for this; they know that their annoying enemies (the humans) use relatively primitive - at least by their standards - ballistic weapons, yet they don't upgrade the Jaffa's armor. There's a reason the humans keep using guns: they work!
* JonasQuinn: [[TropeNamer The original]] Jonas Quinn, no less, although Cameron Mitchell fits the trope better.
* JustFriends: Averted, Subverted, Invoked and Lampshaded with Jack and Sam. Averted: Jack and Sam are forced to admit their feelings, after which they are aware that they both feel the same. Subverted: In the GroundhogDayLoop episode "Window of Opportunity", Jack in one loop takes advantage of the repeating day to give Hammond his resignation for the sole reason of grabbing Sam and [[ShutUpKiss kissing her]]. Invoked: Later on, Carter feels that she and O'Neill won't ever be able to be together, so she begins to date other guys. Lampshaded: A deleted scene from StargateAtlantis indicates that they intend to continue their relationship after O'Neill's retirement.
* JustifiedTrope: The show actually bothers to explain why almost every planet with a gate is suspiciously earth-like [[PlanetOfHats with a single culture]], why the [[BigBad Goa'uld]] are so [[LargeHam cartoonishly over-the-top]] and [[EvilOverlordList take so long to wise up]], why the [[NeglectfulPrecursors precursors were so neglectful]], and more. And if it doesn't get justified, it probably gets [[LampshadeHanging lampshaded at some point]]. Including [[PlayingWithATrope Lampshade Hanging itself]]...
* KickTheWrongDog: Played straight in the series finale when Daniel, having gotten fed up with what he thinks are Vala's intentionally shallow attempts at flirting and seducing him, lashes out with a nearly minute-long rant about her shortcomings that reduces Vala, who actually ''is'' genuinely attracted to him, to tears. It's especially shocking coming from '''Daniel''' of all people, but a close listen as his rant goes on reveals that he shifts from disparaging her actions to voicing his own insecurities and hesitancy about them having a relationship. And when a disturbed Daniel realizes both this and how badly he's hurt her, he quickly lets Vala know that he ''does'' return her feelings. [[SexyDiscretionShot You can guess what happens next.]] And considering that they [[spoiler: [[TheyAllSaidWeNeverCouldBeHappy spend the next fifty years together]] before Sam reverses time]], apparently they work out any remaining issues.
* KilledOffForReal: [[spoiler: Janet Frasier]]
* KilledToUpholdTheMasquerade
* TheKirk: More often than not, Samantha or Daniel.
* KnightsTemplar: Plenty, but particularly the rogue NID, which became the Trust.
* LargeHam: All of the Goa'uld, except for Ba'al occasionally. Anubis in particular did this a lot.
**In all fairness though, they've considered themselves gods for millenia and aren't used to being thought of as less.
* [=~Layman's Terms~=]: Frequent. ''Especially'' whenever Daniel or Sam try to explain something to O'Neill.
* LongRunners: About a decade - and counting, if you include the spinoffs...
* LowerDeckEpisode
* LuddWasRight
* LukeIAmYourFather: Wonderfully played with and [[strike:averted]] torn to shreds during the [[CrowningmomentOfFunny 200th Episode]]. For a moment, you almost believe...!
* MagicalDefibrillator: Averted. When they appear, it seems defibrillators ''are'' used directly to revive someone. Except they never, ever, work. In [=SG-1=], a defibrillator is a total waste of space - it either fails to work on the person they're trying to resuscitate, or the person will revive on their own before the paddles can be applied. Or, occasionally, a while after the defibrillator has failed.
** If that's playing it straight, I'd hate to see what you call crooked.
* MagicFromTechnology
* MagnificentBastard: Ba'al, who manages to cunningly outlast the Ori and all the other Goa'uld, including Anubis, with a combination of [[XanatosGambit devious plans]], a [[AffablyEvil disarmingly charming personality]], a thorough understanding of Earth culture, the technical brilliance to adapt Ancient technology for his own ends, and (during the last couple seasons) [[SendInTheClones plenty of xerox-copy clones]].
** And right there at the end, a ''time machine'' -- which merely exploited an [[ChekhovsGun already-known quirk of the Stargates]] to a logical conclusion that everyone else simply hadn't thought of.
* {{Masquerade}}: TheWorldIsNotReady.
** Lampshaded during the episode ''Small Victories''. [[spoiler: When Thor's Replicator-infested ship is about to descend into Earth's atmosphere, it's said that the President is going to reveal the existence of aliens and the Stargate to the world if they can't shoot it down.]]
***Not that it would have made much of a difference. If the Replicators had taken a real foothold on Earth then before long there wouldn't be anyone left alive to appreciate the disclosure.
* {{The McCoy}}: Jack would often drop the sarcasm to be genuinely concerned about the episode's moral plight... or bug Sam and Daniel incessantly about why they couldn't be BigDamnHeroes ''this'' episode.
* {{MIB}} (NID, who start out as a sometimes-antagonistic, sometimes-allied "The Ends Justify The Means" civilian counterpart to the SGC, but later lose the antagonistic aspects once the shady leaders form a different group.)
* MookFaceTurn: Teal'c, and eventually the entire Jaffa race do a Mook Face Turn into LaResistance and gain independence.
* MoralDissonance: Early on, Daniel kills a vatfull of Goa'uld hatchlings, back when they were thought to be AlwaysChaoticEvil. The fact that they later found some [[MySpeciesDothProtestTooMuch good ones]] should have made him at give at least a ''little'' pause about that incident, but it's never mentioned; the writers may not even have remembered that it happened.
** Not really. The Goa'uld are ''always'' evil. The only good ones are the Tok'ra, and they're a dying race.
*** The Tok'ra are actually the same species as the System Lords. That species is Goa'uld. Most Goa'uld are evil and the team didn't know that until they found the Tok'ra. Remember when they first encountered the Tok'ra and they had to be convinced the Tok'ra weren't evil?
*** The Goa'uld are evil because of a combination of GeneticMemory and [[AppliedPhlebotinum the sarcophagi]]. The Tok'ra queen intentionally chose not to be evil and doesn't pass her memories down AND the Tok'ra do not use the sarcophagus. The Goa'uld are AlwaysChaoticEvil, the Tok'ra have a choice.
* MrExposition: Two of them, Daniel for the culture and Carter for the science. Whenever one of them is missing, the other tends to fill in anyway: any bit of ImportedAlienPhlebotinum will have both 'Goa'uld language' and 'strange radiation'. Jonas is a physicist who's [[{{LeakedExperience}} studied every single one of Daniel's notes]], so he can be either too. (Though Jonas is usually TheWatson during briefings.)
** Even Teal'c can fill this role (though more often in the early seasons), usually in a context of "Yes, I encountered this race/weapon/artifact/person while serving as First Prime to Apophis, and I will now tell you all about it."
** And how can we forget Mr. Cameron "[[AscendedFanboy I've read every mission report EVER]]" Mitchell, who, between the aformentioned mission briefs and his Grandma's wisdom, was a walking pile of GenreSavvy.
* MundaneSolution
* {{MundaneUtility}}: Stargates are used to transport materia (normally people, whole ships in terms of supergates), energy waves (including several transmission frequencies), weapons, in case of one episode a even golf game.
** They can also be used as weapons themselves, showing how Anubis tried to destroy the Earth Gate via a device which fires energy on his gate resulting in energy storage overheat and thus explosion of the other.
** Or they are connected to a black hole and suck up materia from a star resulting in its explosion.
* MythologyGag: Sam's [[DorkAge "Reproductive Organ" speech]] from the pilot returns only to be mocked in later seasons.
* NeglectfulPrecursors: Really, ''really'' bad parents, those Ancients/
* NeverBeAHero: Subverted, sorta.
* NewerThanTheyThink: The P90 is often identified with the Stargate series, but it didn't show up until a third of the way through season 4.
* NightmareFuel: The [[spoiler: Replicator-ized Merrick from ''The Ark of Truth'']] certainly qualifies.
* NoSuchThingAsSpaceJesus
* OmnidisciplinaryScientist: Unless it is a question of archeology or linguistics (Daniel Jackson's area), advanced medicine (the unit's medical staff handle most of that) or midwifery, Samantha Carter has it covered on science.
* OnlyMostlyDead: Daniel, just... Daniel.
* OnlyOneName: Teal'c, later rectified with Teyla and Ronon on StargateAtlantis being given complete names and even military rank for Ronon.
* OnlyTheAuthorCanSaveThemNow: Against the Ori/
* OpenTheIris: Actually about eyes, so it's only the TropeNamer, [[ThisIndexIsNotAnExample not an example]].
* OperationJealousy: [[AlternateUniverse Alternate]] Carter: "I'm kind of attracted to Daniel."
* OurWormholesAreDifferent: The most prominent being the ones connecting stargates of course.
* OurPresidentsAreDifferent: Depending on the universe and timeline.
* PathOfInspiration: "Hallowed are the Ori."
* PerfectPacifistPeople: The Nox.
* PlanetOfHats: Many.
* PrettyLittleHeadshots: How Mitchell finally gets rid of [[spoiler: Ba'al]] in ''Continuum''.
* ProudWarriorRaceGuy: At least two different cultures, in two different galaxies, both of which produce a main character.
* PortalSplat: The Stargate is open as long as the directors say, so it's not unusual for characters to miss the wormhole. Also, when the iris is closed on the receiving end of a wormhole, anything that attempts to travel through it suffers a 'bugs on a windshield' death. O'Neill coldly orders this done to [[spoiler:poor old Rene Auberjonois]], but to be fair he was a [[spoiler:[[DoesThisRemindYouOfAnything racist supremacist leader]]]].
* PowerWalk: SG-1 frequently enters the Stargate (and exits the other side) in this manner. In fact, the times they don't PowerWalk usually indicate that [[OhCrap something is wrong]].
* ProductPlacement: In one of the best uses of this trope, Samantha Carter uses a Dell Inspiron laptop in the first 8 seasons of the show. Though it could have originally been considered as a [[TheRedStapler Red Stapler effect]], her switching to a Dell XPS in season 9 sealed the deal.
** In one episode in season 10, Col. Mitchel and another Col. Mitchel from another universe are seen sitting at a table drinking Aquafina-brand bottled water. [[WhatDoYouMeanItsNotAwesome while having an argument in which the fate of three galaxies hang in the balance.]]
* PublicDomainArtifact: Everything from the Sword in the Stone to Thor's Hammer. Usually ImportedAlienPhlebotinum of some sort.
* PunctuationShaker
* RageAgainstTheHeavens: Strictly against the Ori, but they are clearly a thinly disguised version of a popular real life religion [[spoiler:although after defeated, people admit the teachings aren't bad, it was the soul stealing it was used for]].
** Taken to its logical most extreme.
* RagnarokProofing: Ancient technology still works after being abandoned for a million years.
* RecycledTheSeries
* RedShirt: Virtually every [[StealthPun Russian]] character that stepped through a Stargate. (Lampshaded, as the Russians angrily point this out. In fact, you could say they're something of a [[IncrediblyLamePun Red Army]])
**The SGC's [[http://en.wikipedia.org/wiki/United_States_Air_Force_Security_Forces Security Forces]] during just about every single [[AllYourBaseAreBelongToUs foothold situation]].
* RelationshipUpgrade: Daniel and Vala in the series finale, though [[spoiler: it gets undone by the time reversal]].
* ReluctantWarrior: Daniel Jackson.
* RememberWhenYouBlewUpASun: TropeNamer
* ResetButton: Used very rarely (except in time-travel episodes), and then [[strike:never]] usually not without some kind of repercussions for using the button itself.
** In the series finale, though, there was a ''literal'' reset button... which ''still'' had a somewhat drastic repercussion for one of the characters.
* RoadRunnerVsCoyote: "The Bounty"
* RockBeatsLaser: Earth's conventional firearms and other conventional weapons are usually quite adequate against the supposedly more advanced enemy alien armies they fight.
* RoleAssociation: The title card says Richard Dean Anderson, your brain reads [=MacGyver=].
** Unless you're under a certain age, in which case it's really weird to see Jack O'Neill with a mullet when you catch the odd ''[=MacGyver=]'' rerun.
* TricoloursWithRustingRockets: The Russians manage to acquire a Stargate and briefly run their own programme. Later, Russian officers are part of the international programme.
* ScaryDogmaticAliens: The Goa'uld and especially the Ori.
* [=~Screw The Rules, I'm Doing What's Right~=]: This trope is used quite a bit.
** In the first season episode ''Enigma'', Daniel Jackson goes against orders to help the Tollan get to their stargateless new world.
** In the first season finally ''Within the Serpent's Grasp'' the whole of [=SG1=] disobeys orders to launch a first strike against Apophis and his assault upon the planet after the ObstructiveBureaucrat and CorruptBureaucrat [[WhatAnIdiot Senator Robert Kinsey]] shuts down Star Gate Command.
** In the Ori arc, three ascended ancients are shown to do this to help humanity.
** In the pilot episode, [[SpellMyNameWithAnS O'Neil(l)]] admits, in his roundabout way, that on the [[{{Stargate}} first trip]], he didn't fulfill the mission to the letter, because a) genocide against the Abydonian slaves wouldn't be right, and b) technically, they ''did'' nuke Ra, who was the actual threat.
* TheScrappy: Makepeace, which makes it all the more satisfying when [[spoiler: he turns out to be TheMole]].
** To some fans, Vala.
* SeasonFinale
* SendInTheClones: Ba'al's clones (to great comedic effect) and, to a much lesser extent, [[spoiler: The Asgard]].
* {{Shipping}}: Lots and lots of shipping, hetero and slash alike.
* ShirtlessScene: Daniel Jackson, and often. In fact, this should probably be Butt Naked Scene when it comes to him.
* ShowWithinAShow: "Wormhole X-Treme!", used twice to great comedic effect, including the celebrated 200th episode.
* ShoutOut
** Carter's "It took fifteen years and three supercomputers to [=MacGyver=] a way to open the gate" line, improvised by Tapping.
** O'Neill wanted to call the Prometheus the [[StarTrek Enterprise]].
** Used with glee in "1969," with plenty of Star Wars references.
** Don't forget Daniel calling himself "Hans Olo" in ''Prometheus Unbound''.
*** In ''Tangent'' he claims to be "The Great and Powerful Oz."
** The American submarine briefly mentioned in the episode "Small Victories" as being ready to destroy the Russian sub is named [[TheHuntForRedOctober ''Dallas'']].
** Walter "The Chevron Guy" Harriman. (His first name is a shout out to Walter "Radar" O'Reilly, and he actually pulls a Radar in the first episode of Season Nine: "Sir, the personnel files you're about to request are right there on your desk.")
** There are a whole lot of [[TheSimpsons Simpsons]] references, since it's O'Neill's favorite show.
* SingleBiomePlanet: Common, but implied to be due to mistakes by the charachters in assuming the small area they explore is what the whole planet is like. One member concluded Earth was an ice planet when she ended up in Antarctica.
* SisyphusVsRock
* SortingAlgorithmOfEvil
* SpockSpeak: Teal'c. Indeed.
* StandardizedLeader: Averted. O'Neill was mainly mourning his son in the original movie, but his character wasn't really fleshed out. So he would have been this trope in the series had that not changed.
** Unfortunately shows a little bit of this in ''StargateUniverse'', where he's a minor supporting character.
* StargateCity: This show is how Vancouver got that nickname.
* StockFootage: The gate dialing and opening - sometimes subverted with powerful effect when things go wrong.
* StoryArc: At least one per season.
* SufficientlyAdvancedAlien: ''Lots'' of them. The Asgard, the Goa'uld, the Ancients, and those are just the ones that aren't ''technically'' a PlanetOfHats, I haven't even gotten to the Nox or the Tolans or... you get the idea.
** In the end, it turns out that humanity is playing catch-up in terms of technological achievements...with ''everyone''.
*** Which means, towards the end of the series Earth now has technology from ''all'' of them to use in their own spaceships.
* TakahashiCouple: [[GenderFlip Gender Flipped]] with Vala as the JerkWithAHeartOfGold and Daniel as a type "B" {{Tsundere}}.
* TastesLikeFriendship: Daniel feeds random alien, random alien becomes his friend.
* TearJerker: The season 1 episode, 'Torment of Tantalus'. arnest, having been alone on a world for 50 years with no human contact (the Stargate lost power and closed just after he went through, his bosses assumed he was dead and never went after him), hugs Daniel and says, tearfully, "About time."
** This troper was more confused that he hasn't gone insane.
*** He did. Unless seeing your wife when she isn't even on the same planet as you is normal.
** The seventh-season episode "Heroes." The in-show tribute video at the end actually did bring tears to General Hammond's actor, a former Vietnam-era army sergeant. And for the regular viewers... [[spoiler:fan-favorite regular Dr. Frasier is killed instantly while treating a wounded airman during an offworld firefight. Her memorial service consisted of a list of names of people she saved during her time at Stargate Command.]]
* TechnoBabble: Mostly courtesy of Carter, [=McKay=], and a couple of others.
** O'Neill serves as a bit of a GreekChorus when this happens, speaking on behalf of sci-fi fans everywhere. He either interrupts Carter to ask a simple "yes or no" question, or else irritatedly inform her that he ''does'' know what photosynthesis and supernovas are, thank you.
* TemporaryLoveInterest: Several.
* TheHathorEffect: TropeNamer
* TheyCalledMeMad: Daniel Jackson and his grandfather.
* TimeCompressionMontage: ''Unending'', the series finale, had one of these, set to Creedence Clearwater Revival's "Have You Ever Seen The Rain?"
* TimeForPlanB: O'Neill likes to poke fun at this line.
-->'''Reynolds:''' "Not much faith in Plan A?"
-->'''O'Neill:''' "Since when has Plan A ever worked?"
* TimeTravel: Multiple times, including alternate timelines.
* TouchedByVorlons: Daniel, Anubis, Priors, Carter and O'Neill.
* TeleportersAndTransporters: The Gates, the Rings, Asgard beaming.
* TheUmbridge: General Bauer in "Chain Reaction".
* {{Tretonin}}: TropeNamer
* TwoKeyedLock: Sometimes it's passwords, sometimes it's keys.
* UnCanceled: Seasons 5, 6, 7, and 8 were expected to be the last. The non-renewal after season 10 was totally unexpected..
* UngratefulBastard: The [=SG-1=] after partnership with just about any Goa'uld or Ori.
* UnusualEuphemism: "I told her that she should attempt procreation...with herself."
* VillainPedigree: The Ori and Replicator pull this on the Goa'uld.
* VoiceOfTheLegion
* WastelandElder: Several, usually one per AdventureTown-- err, planet.
* WeHaveForgottenThePhlebotinum: Several cases of needing something from another base, planet, or needing a bit of [=MacGyvering=] to make a new Doohickey.
* WhamEpisode: Again, in the episode ''Heroes'', the [[spoiler: death of Dr. Janet Fraiser]]. To add extra oomph, KilledOffForReal is played with in this episode, as two characters receive potentially fatal wounds before it's revealed quite shockingly that [[spoiler: Janet]], who the viewer doesn't even know got injured, is the one who actually died.
* [[{{Ptitle5fz4u602}} Who's On First?]]: The Goa'uld Yu resulted in some of this/
* WhyAmITicking: Cassandra
* WireDilemma: All the wires are yellow, so [[NoTimeToThink Jack has to guess which to cut]].
-->'''Col. O'Neill:''' I'd like to take this opportunity to say that [[LampshadeHanging this is a very poorly designed bomb]], and I think we should say something to somebody about it when we get back.
* TheWoobie: Daniel, perhaps?
*WordOfGod: The cast has at times spoken about what ''they'' think was going on between the scenes and time-skips in the series finale, "Unending." In particular, Amanda Tapping and Christopher Judge said they played their interactions to imply Carter and Teal'c had developed a relationship, and either Claudia Black or Michael Shanks (this troper forgets which) said the reason Vala's crying in one scene is because she miscarried.
* TheWorldIsAlwaysDoomed
--> '''Mitchell:''' I think that was dealt with when you guys saved the world for the sixth or seventh time.
--> '''O'Neill:''' Ah, who's counting?
--> '''Mitchell:''' T'ealc, apparently. He mentions it quite a lot.
* XanatosGambit: Good guys and bad guys alike had loads of them.
* YearInsideHourOutside: In the series finale, Sam does this to keep the ''Odyssey'' from getting blown to smithereens while she uses the extra time to try and figure a way out of danger. The good news is that she succeeds. The bad news is that [[spoiler: it takes her fifty years]].
* YouCantGoHomeAgain
* YouHaveGOTToBeKiddingMe: Practically O'Neill's catchphrase in later seasons.
