-->-- Opening narration to ''Capcom vs. SNK''

During the height of the {{fighting game}} popularity, one of Creator/{{Capcom}}'s biggest competitors was Creator/{{SNK}}, creators of the Platform/NeoGeo console and arcade system, who challenged ''Franchise/StreetFighter''[='=]s dominance with a wide array of linked and standalone games and series, culminating with their own MassiveMultiplayerCrossover, ''VideoGame/TheKingOfFighters''. Naturally, in 1999 and 2000, the [[TemptingFate inevitable]] [[VideoGame/CapcomVs happened]], and the two companies came together to both make separate fighting games based on the concept.

The fighting games of this series, so far, are these:[[note]]The company listed first is the developer.[[/note]]
* ''[[VideoGame/SNKVsCapcomMatchOfTheMillennium SNK vs. Capcom: The Match of the Millennium]]''
* ''VideoGame/CapcomVsSNKMillenniumFight2000''
** ''Capcom vs. SNK Pro'' (an UpdatedRerelease that, among other things, added Dan Hibiki and Joe Higashi to the roster)
* ''[[VideoGame/CapcomvsSNK2MarkoftheMillennium Capcom vs. SNK 2: Mark of the Millennium 2001]]'' (known as ''Capcom vs. SNK 2: Millionaire Fighting 2001'' in Japan)
** ''Capcom vs. SNK 2 EO'' (a modified version for Platform/{{Xbox}} and Platform/NintendoGameCube that adds an "Easy Operation" ("GC-ISM") mode for simple inputs and changes certain gameplay behaviors)
* ''VideoGame/SNKVsCapcomSVCChaos''

SNK also developed three {{Card Battle Game}}s based on the concept (the ''[[VideoGame/SNKVsCapcomCardFightersClash Card Fighters Clash]]'' series), the most recent for the Platform/NintendoDS ending the ''SNK'' series as a whole and notoriously containing a GameBreakingBug.

While no direct sequels were made to any of the games here since the late 2000's, Capcom and SNK characters went on to have GuestFighter appearances in other games:
* ''VideoGame/Tekken7:'' While not part of the game at launch, Akuma and Geese joined the roster through updates, both bringing modified versions of their 2D move lists with system mechanics based on ''VideoGame/StreetFighterIV'' and ''[[VideoGame/TheKingOfFighters The King of Fighters XIV]]''.
* ''VideoGame/GranblueFantasy:'' As part of two collaboration events, characters from ''Franchise/StreetFighter'' and ''VideoGame/SamuraiShodown'' can join the player's collection of heroes; Ryu, Chun-Li, Haohmaru and Nakoruru can be recruited via this method.
* ''VideoGame/SuperSmashBrosUltimate:'' Ken (as part of the launch roster) and Terry (via DLC) join the ''Smash Bros.'' series in this installment of Nintendo's premier MassiveMultiplayerCrossover, joining Ryu & Mega Man - [[VideoGame/SuperSmashBrosForNintendo3DSAndWiiU veteran fighters with one appearance each to their names.]]
* ''VideoGame/TheKingOfFightersAllStar'': Possibly the closest yet to a full-on follow-up, this mobile game has done two ''Street Fighter'' events that added characters from that series as units. The first added Ryu, Chun-Li (in both her classic and ''Street Fighter Alpha'' versions), M. Bison, Luke and Akuma, and a second one in 2023 added ''VideoGame/StreetFighter6'' characters Guile, Cammy, Juri, Jamie, and Ken (with Guile and Cammy's classic versions also available).

As of 2022, there are discussions between Capcom and SNK to revive the series. Though there has been no news on a new game yet, ''SNK vs. Capcom: Match of the Millenium'' has been ported to Platform/NintendoSwitch and PC as has the first ''Card Fighters Clash'' game for the Switch.

!Examples of the series in general:
* BattleIntro: The games are full of this. From the ''[=CvS=]'' duology alone do you get cool scenes like Geese throwing a Reppuken at Bison to blow his cape away.
* DemotedToExtra: Characters such as Robert Garcia, Mature, Daimon, Yang and Andy get only passing mentions, assist roles, or cameos, in the entire ''Capcom vs. SNK'' series. This is very noticeable in the SNK side, because most of the ''KOF'' teams (sans the Women Fighters Team) are incomplete in the games. For example, the Art of Fighting Team lacks Robert, the Fatal Fury Team lacks Andy, the Japan Team lacks Goro Daimon, the Villain Team lacks Billy Kane, and so on. Chang also shares his moveset with Choi in ''Capcom vs. SNK 2'', but Choi got into ''SNK vs. Capcom: SVC Chaos'' with Chang only getting cameos.
* {{Irony}}: The SNK-side art for both ''Capcom vs. SNK'' games is done by famed SNK artist Creator/{{Shinkiro}}. However by that point SNK had gone under and Shinkiro was working as an artist for Capcom (with the original game being one his first major projects for the company, no less).
* ShoutOut: Check [[ShoutOut/CapcomVs the page]].
* SpotlightStealingSquad: The ''Street Fighter'' cast, who always make up more than half the Capcom side characters (both Capcom-published games include all 12 original World Warriors in their roster - ''SVC Chaos'' saw Zangief, Blanka and Honda miss the cut). Some of the cases would be more appropriate to call ''Street Fighter vs. SNK''. To be fair, the majority of the SNK side is comprised of characters who've already appeared in a ''King of Fighters'' game, so ''Street Fighter vs. The King of Fighters'' would be a better title[[note]]Although a good part of the ''KOF'' cast is either from ''VideoGame/FatalFury'' or from ''VideoGame/ArtOfFighting'', so there's that.[[/note]].
** The first game at the very least had Morrigan and Nakoruru, who come from series (''VideoGame/{{Darkstalkers}}'' and ''VideoGame/SamuraiShodown'') outside of both ''Street Fighter'' and ''KOF''. The second one introduced more characters from outside those games (''VideoGame/FinalFight'' and ''VideoGame/RivalSchools'' as well as other SNK participants who haven't been or had yet to be in a ''KOF'' game like [[VideoGame/FatalFury Rock]], [[VideoGame/SamuraiShodown Haohmaru]], and [[VideoGame/TheLastBlade Hibiki]]). ''SVC Chaos'' saw [[VideoGame/MetalSlug Mars People]], VideoGame/{{Athena}}, [[VideoGame/GhostsNGoblins Red Arremer]] and [[VideoGame/MegaManX Zero]] (in his ''VideoGame/MegaManZero'' incarnation) join the fray.
