Street Fighter Alpha: Warriors' Dreams, known as Street Fighter Zero (ストリートファイター ZERO) in Japan, Asia, South America, and Australia, is a 1995 fighting game by Capcom originally released for the arcade for the CP System II hardware. It was the first all new Street Fighter game produced by Capcom since the release of Street Fighter II in 1991. The working title for the game was Street Fighter Legends.

The game introduces several new features, expanding on the Super Combo system previously featured in Super Street Fighter II Turbo, with graphics drawn in the same cartoonish style Capcom employed in Darkstalkers and X-Men: Children of the Atom. The plot of Street Fighter Alpha is set after the original Street Fighter but before Street Fighter II and thus the game features younger versions of established characters, as well as characters from the original Street Fighter and Final Fight, and a few who are new to the series.
