is a 1999 fighting game developed and published by Capcom for arcades. It is the second and final updated version of Street Fighter III, following Street Fighter III: 2nd Impact. Like its predecessors, it runs on the CP System III hardware.

3rd Strike increased the character roster by adding five new characters, notably including Chun-Li. It also added further refinements to the previous game's play mechanics and rules, including improvements to the parry system. It was ported to the Dreamcast in 2000. In 2004, it was released on the PlayStation 2 and Xbox as part of the Street Fighter Anniversary Collection. A downloadable online version titled Street Fighter III: 3rd Strike Online Edition was released on PlayStation 3 and Xbox 360 in 2011.

Although not very popular upon release, it amassed positive reviews, and eventually gained a large cult following years after release. The game has a significant competitive gaming scene, which included Evo Moment 37 (also known as the "Daigo Parry"), often considered the most iconic moment in competitive gaming history. On May 29, 2018, Street Fighter III: 3rd Strike was released as a part of the Street Fighter 30th Anniversary Collection for the Nintendo Switch, PlayStation 4, Windows, and Xbox One.

Gameplay Released in May 1999, the third and final installment of Street Fighter III brought back the classic Street Fighter II character Chun-Li, along with four new characters (Makoto, Remy, Q, and Twelve), extending the selectable roster to 19 characters, with AkumaOfficial Street Fighter 3 3rd Strike Akuma character biography (in Japanese): "Fist Master"... Akuma. A ferocious yet pure obsession with "fighting". Carrying tens of thousands of dead people on his back, he wanders between the underworld and the real world in search of the next strong man.

All of the returning characters from the previous Street Fighter III games were given new stages, endings, and voice actors for certain characters, continuing the overall storyline from where the first two games left off.

The commands for air parries, throws/holds, and leap attacks were changed from 2nd Impact. Additionally, the player can perform a "Guard Parry" or a parry during a guard stun if the timing is right. A "Guard Parry" is also known as a "Red Parry" because the character turns red when performing it. The game also introduces a grade-based "Judgement System", in which the winning player in a single or two-player match is graded after the match based on offense, defense, techniques, and extra points. Special points are also awarded after fulfilling specific requirements.

The single-player mode consists of fighting ten regular opponents, which includes a character-specific rival as the penultimate opponent and Gill as the final boss for each of the characters except for Gill himself, whose final boss is Alex. Despite his status as a regularly selectable character, the CPU version of Q can only be fought in the single-player mode as a secret challenger. The "Parry the Ball" minigame from Street Fighter III: 2nd Impact returns as well as a new version of the "Crush the Car" minigame from Street Fighter II.

Characters and timeline All the characters from 2nd Impact returned, with the exception of Shin Akuma, a computer-controlled version of Akuma with more powerful techniques (although the character still exists in the game's code).

Release Street Fighter III: 3rd Strike was originally released for the arcades in 1999. There are three revisions of the arcade board, with differences in bugs and gameplay mechanics (specifically, "unblockables" for the characters Urien and Oro).

The Dreamcast version was released in 2000. Like Double Impact, this version features an Arcade, Versus, Training (with normal and parry training) and Options modes, as well as a "System Direction" mode which allows the player to adjust several of the game's features. Like in Double Impact, Gill can be selected by the player, but only after fulfilling certain requirements. Also, one additional remix of each character's musical theme, not present in the original arcade version, was composed for this version, and it was played during the third round of each match. These additional remixes were also included in the PlayStation 2 version. This version was based on the third revision of the game that removed the "unblockables" for some characters. In this version, by clearing the game with every character including Gill, the extra options, such as infinite super arts, will be available for toggling on/off. It did however introduce significant lag that EVO 2004 players opted to play on the original arcade version as the definitive version of the game.

A PlayStation 2 version of 3rd Strike was released in 2004, with all of the features from the Dreamcast version, including a choice between the arcade and Dreamcast version's respective soundtracks, but based on the earlier arcade revisions with "unblockables" intact. It was released in Japan as a standalone game, with a limited edition package containing an All About Street Fighter history book, a 500-piece jigsaw puzzle, and a strategy DVD. The PS2 version was released in North America as part of the Street Fighter Anniversary Collection, a two-in-one bundle that also includes Hyper Street Fighter II. The PS2 version was not released in the PAL region. The PS2 version was re-released in Japan on September 18, 2008, in a two in one bundle with Capcom vs. SNK 2.

An Xbox version of the Street Fighter Anniversary Collection was also released during the year in all three regions. The Xbox version of 3rd Strike includes all of the features from the PS2 version, as well as an online Versus mode.

Online Edition At the 2010 San Diego Comic-Con, Capcom announced that an online edition of 3rd Strike titled Street Fighter III: Third Strike Online Edition was in development. The game features enhanced visual settings and GGPO-built online play. The version was done by Iron Galaxy Studios and has similar features to Final Fight: Double Impact, including visual filters, an optional remixed soundtrack by Simon Viklund, and bonus content unlocked by completing in-game achievements. Other new modes include Tournament and Spectator modes, as well as Trial modes that teach the game's fundamentals and the ability to share replays on YouTube.
