Street Fighter Alpha: Warriors' Dreams, known as Street Fighter Zero in Japan, Asia, South America, and Oceania, is a 1995 fighting game developed and published by Capcom for arcades. It was the first all new Street Fighter game produced by Capcom since the release of Street Fighter II in 1991. Plotwise, it serves as a prequel to Street Fighter II and thus features younger versions of established characters, as well as characters from the original Street Fighter and Final Fight.

The game introduces several new features, expanding on the Super Combo system previously featured in Super Street Fighter II Turbo, with graphics drawn in a similar art style to the one Capcom employed in Darkstalkers and X-Men: Children of the Atom. After its arcade release, it was ported to PlayStation and Sega Saturn home consoles. Street Fighter Alpha received a mainly positive reception; it was followed up by Street Fighter Alpha 2 in 1996 as part of the Alpha sub-series.
