'''''Street Fighter Alpha: The Animation''''', released in Japan as '''''Street Fighter Zero: The Animation''''' (ストリートファイターZERO?) and also known as '''''Street Fighter Alpha: The Movie''''', is a 1999 [[{{OriginalVideoAnimation}} OVA]] film loosely based on the ''VideoGame/StreetFighterAlpha'' series. It was directed by Shigeyasu Yamauchi, with character designs by Yoshihiko Umakoshi. An English adaptation was produced by MangaEntertainment and released in 2000.

The film commemorates the tenth anniversary of the arcade release of the original ''VideoGame/StreetFighterII''. It is not a prequel or sequel to either ''Anime/StreetFighterIITheAnimatedMovie'' or ''Anime/StreetFighterIIV'', but an independent installment, although a handful of voice actors from the previous adaptations reprised their roles for the English version.

The story starts when Ryu is thinking of Gouken's death, then intervenes in a shoot-out to help Chun Li. Few afterwards, he and Ken are contacted by a boy named Shun -- who claims to be Ryu's younger brother! Neither is really convinced by Shun's claim, but they decide that there's no harm on letting the boy tag along with them. Things start getting hairy, however, when the three decide to enter the Street Fighter tournament: not only Ryu is starting to show more and more sympthoms of the Satsui no Hado awakening within him, but Shun's background and the persons behind it start to unfurl...

* {{Flanderization}}: Poor Dan gets curbstomped even more than usual.
* GenericDoomsdayVillain: Dr. Sadler and his cyborg have literally no other characterization besides being fodder for Ryu's Hadouken. And besides Ryu's Hadouken, [[InvincibleVillain nothing else hurts them]].
* LongLostSibling: Shun claims to be Ryu's younger brother. He and Ken don't believe him at first, yet they still let him hang around them... but there are also some ''really'' troubling details about the kid [[spoiler: like him apparently being able to summon ''the Satsui no Hado'']]...
* MorallyAmbiguousDoctorate: Dr. Sadler.
* StealthMentor: Rose tries to be this to Ryu.
