Street Fighter is a fighting game franchise created by Capcom. It began with the original arcade game, which introduced players to one-on-one martial arts combat against a lineup of opponents from around the world. The series grew into a flagship for the fighting genre, with sequels, revisions, and crossovers appearing across arcades and home consoles over the following decades.

The franchise is best known for its roster of international fighters and for the rise of the World Warrior tournament, the setting that gives many of its entries their shape. Moves such as the hadouken and the shoryuken have become shorthand for the genre, and the series is widely credited with helping establish the competitive fighting game scene. New challengers keep arriving, and every round is still decided the same way: two fighters, no retreat, one victor.
