Champion Boxing (チャンピオンボクシング, "Boxing Champion") is a 1984 boxing sports video game developed and published by Sega for the SG-1000, and later ported to the arcades, only in Japan and Europe. It was Sega-AM2 founder and leader Yu Suzuki's debut creation, as well as that of Rieko Kodama. In 1985, a successor of Champion Boxing titled Champion Pro Wrestling was released in the arcades, and ported to the SG-1000 and the MSX home computer the same year. However, this is a professional wrestling game instead of a boxing game.
