Some shows love playing genre conventions, a FantasyKitchenSink will have everything in the mythological handbook and then some, TropeOverdosed works will keep adding tropes so long as they run, and then there are even shows [[TropeMaker that make new tropes.]]

These are not those shows. (Or can they be?)

A Sci-Fi Kitchen Sink is for all intents and purposes the playground of Science Fiction Tropes and everything associated with them. Have an ArtificialIntelligence construct able to run the CoolStarship? It makes you coffee in the morning. HumongousMecha? You walked by several on the way to work. FasterThanLightTravel? [[CasualInterstellarTravel Totally mastered to the point where even Joe Penniless can get a ride to the stars.]] [[BeamSpam Laser and particle beams as weapons?]] Everybody and their dog has one. The list of possible areas seems to be endless.

A good way to tell if a work is a Sci-Fi Kitchen Sink, is ask three questions. Is it in the SciFi genre? [[MohsScaleOfSciFiHardness Is it softer than reality by a wide margin according to the scale?]] Does it use all or much of the stuff in the genre of SciFi and not [[LampshadeHanging Hang A Lampshade]] on it? Answer yes to all three and you likely are dealing with a Sci-Fi Kitchen Sink.

Popular in SpaceOpera. Also popular in MegaCrossover fanfic. Naturally compare FantasyKitchenSink; when both sinks are combined, it becomes ScienceFantasy. See also StandardSciFiSetting, a particularly popular instance of Sci-Fi Kitchen Sink.

[[folder:Film]]
* ''Franchise/StarWars'' is a kitchen sink of MilitaryScienceFiction, SpaceOpera and HighFantasy tropes.
[[/folder]]

[[folder:Literature]]
* ''Literature/{{Spectral Shadows}}'' could qualify for this. There's a {{Mad Scientist}}, a world in a time that takes place {{After the End}}, there's {{Time Travel}}, {{Funny Animal}}s that evolved from genetic slag due to weaponized acid rain, there's an intergalactic empire of {{Space Pirates}}, android funny animals, a [[{{TheMatrix}} virtual reality rpg where one can learn powers at the expense of feeling any and all pain]], world warping powers, a space ship that can travel time and space, humongous mechas, and more.
* In the universe of [[Creator/IainBanks Iain M. Banks]]'s hyper-advanced people, Literature/TheCulture, there's everything from dystopian ultra-capitalist planets, small debauched backwaters, "Sublimed" civilisations living in entire other dimensions, neglectful precursors, {{Proud Warrior Race}}s, post-singularity communist civs...well, you get the idea. The fact that this is just a very incomplete list of some of the civilisation types should tip you off to the fact that this series mixes-and-matches an awful lot of sci-fi tropes. Tech levels vary right alongside the civilisations, although we rarely see a world a great deal less developed than present day Earth. Expect to see SciFiWritersHaveNoSenseOfScale stunningly averted, in both range and size of ships, drones, space battles, androids, sentient space-suits, conspiracies and counter-conspiracies.
* PerryRhodan is running for over 50 years now and did start with TheSpaceRace and then features things like AncientAstronauts, SufficientlyAdvancedAlien, AscendToAHigherPlaneOfExistence, TheBattlestar, CosmicChessGame, LensmanArmsRace, OrderVersusChaos, and and ... and we have not nearly covered everything in the first one hundred books.

[[/folder]]

[[folder:Live-Action TV]]
* ''Series/DoctorWho'', by virtue of it having run from 1963 to 1989 and subsequently from 2005 onwards and ranges through the entirety of time and space. After 30+ years on-air, that's a lot of sci-fi ideas.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/{{Warhammer 40000}}'' - sometimes it is like each army is there to be a representative of a different sort of science fiction. Your SpaceMarines are your, unsurprisingly, post-[[Creator/RobertAHeinlein Heinleinian]] SpaceMarines, Tyranids are books are about BugWar, Tau are {{aminesque}} mecha and firepower and TheFederation, Eldar are ClarksThirdLaw SufficientlyAdvancedAliens, spaceship battles feel like they come out of the ''Literature/HonorHarrington'' universe, Necrons are TheTerminator and so on. If anybody want to write about or parody a certain type of science fiction, then they can.
* ''TabletopGame/{{Trinity}}'' was launched as one of these as well. You want cyberpunk? America's corporate-owned and full of technopaths. You want wasteland? Paris and a huge chunk of the surrounding land got nuked. You want SpaceOpera? Mankind's made first contact and is currently involved in political dealings with at least three different species. You want PsychicPowers? What flavor do you want them in?
[[/folder]]

[[folder:Videogames]]
* The ''Franchise/{{Halo}}'' series including its ExpandedUniverse. It has HumongousMecha, FasterThanLightTravel, ArtificialIntelligence, SpaceMarines, {{Precursors}}, etc. While the weirder aspects of SciFi like PsychicPowers or various {{Negative Space Wedgie}}s haven't show up in the games (although the [[TheVirus Flood]] HiveMind, Slipspace anomalies, and the [[spoiler:Ur-Didact's]] [[MagicFromTechnology gravity control powers]] come close), ''Literature/TheForerunnerSaga'' dips into that territory [[spoiler:by going the CosmicHorrorStory route, complete with {{Eldritch Starship}}s, GeniusLoci, and a SentientCosmicForce which allows technology to be made of ''thought'']].
* ''VideoGame/{{Starcraft}}'': Everything can travel faster than light via PsychicPowers, science or biological creatures able to do so on their own! AI exists but is lower key, {{Starfighter}}s abound as do HumongousMecha and [[TankGoodness Tanks]] and more.
* ''Franchise/MassEffect'': Combines everything in SpaceOpera genre together in a single package.
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/AxeCop'' uses a wide variety of sci-fi tropes in creative (and frequently [[CrazyAwesome ridiculous]]) ways.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/{{Futurama}}'': Everything that exists in the Sci Fi Writer's Handbook exists here plus a heaping helping of RuleOfFunny and ItRunsOnNonsensoleum. If it hasn't found some way of being incorporated well it likely will be.
