Black Belt is a side-scrolling single-plane beat 'em up game released for the Master System in 1986. It is a localization of the Japanese Mark III game, Hokuto no Ken (北斗の拳), based on the manga and anime series of the same name (which would later be published as Fist of the North Star in English). The export version was released without the Hokuto no Ken license, forcing graphic alterations to the game. Black Belt was one of programmer Yuji Naka's early games prior to his involvement in Sonic the Hedgehog.
