Virtua Fighter is a fighting video game developed and published by Sega for arcades. It was developed for the Sega Model 1 arcade platform by AM2, a development group within Sega headed by Yu Suzuki. An early prototype version was location tested in Japan by August 1993, before the complete game was released worldwide in December 1993. It was the first arcade fighting game to feature fully 3D polygon graphics. The game was ported to Sega Saturn as a global launch title in 1994 and 1995, and also received a port to the Sega 32X.

The game was critically acclaimed and a major hit, becoming one of Sega's best-selling arcade games of all time with more than 40,000 arcade units sold while the Saturn versions sold over 1 million copies. Virtua Fighter was highly regarded for its in-depth 3D fighting engine and real-world fighting techniques, and has been revolutionary and highly influential in the evolution of the genre and video games in general. Its success led to the Virtua Fighter series, with its sequel Virtua Fighter 2 released in 1994.

In 1995, an update titled Virtua Fighter Remix was developed and released by AM1, featuring drastic graphical improvements. This improved version was quickly ported to the Saturn console and later also received a port to Microsoft Windows. The game's remake, Virtua Fighter 10th Anniversary, was released for the PlayStation 2 in 2003 as a stand-alone title in Japan and as a bonus to Virtua Fighter 4: Evolution in North America.
