Akitoshi Tamura (born May 31, 1980 in Japan) is a mixed martial arts fighter from Japan. He competed almost extensively in the Shooto organization, before making his debut at the WEC 37. In 2007, he was the lightweight champion of Shooto. He was named #7 featherweight in 2008 by MMA Worldwide. Tamura is a freestyle fighter.

Tamura made his professional debut in the Shooto organization in a fight against Eiji Murayama, in August 2001, and lost on a technical decision (he later returned to face Murayama in 2004, only for the match to end in a draw). He has made MMA headlines when he defeated Takeshi Inoue in 2007, which won him the title of Shooto lightweight champion. He has also participated in GCM and MARS events, achieving a TKO over Masaomi Saito in the former, and a first round submission over Ian Loveland in the latter.

Akitoshi Tamura made his WEC debut at WEC 37. Althought Akitoshi had a reputation of being one of the world's best in his weight class, he lost to former IFL featherweight champion Wagnney Fabiano, for whom it was also his WEC debut. For his next fight, Tamura will make his 135 lb. Bantamweight debut at WEC 40 against former title challenger Manny Tapia.
