Fatal Fury: King of Fighters, released in Japan as Garou Densetsu: Shukumei no Tatakai (餓狼伝説 宿命の戦い, "Legend of the Hungry Wolf: The Battle of Destiny") is a 1991 head-to-head fighting game released by SNK for the Neo Geo arcade and home platforms.

This game was SNK's first fighting game for the Neo Geo system (released a few months after the arcade release of the original Street Fighter II) and served as the inaugural game in their Fatal Fury series, as well as the first game to depict the fictional "King of Fighters" tournament (which became the basis for the later The King of Fighters games). Many of SNK's mainstay characters, including the Bogard brothers Terry and Andy, and their arch-nemesis Geese Howard, made their debut in this game.
