Brian Fish (born December 20, 1965) is an American college basketball coach, most recently serving as head coach for the Montana State Bobcats men's basketball team.^[1] Fish is currently the director of player personnel for the University of Georgia Bulldogs basketball team.^[2]

A first-team all-state selection from Seymour High School in Indiana, Fish went on to play college basketball at Western Kentucky and Marshall. He graduated from the latter in 1989.^[3][4]

After graduation, Fish served as a graduate assistant at his alma mater under first-year head coach Dana Altman. He would stay on staff with the Thundering Herd until 1992, when he would rejoin Altman at Kansas State from 1992 to 1994, and follow Altman to Creighton where he served as an assistant from 1994 to 1996. Fish joined Billy Tubbs staff at TCU, and served as an assistant coach until 2002.
