Brian M. Lewis (born December 5, 1974) is an American athlete, winner of gold medal in 4 × 100 m relay at the 2000 Summer Olympics.
Born in Sacramento, California, Brian Lewis played baseball (his father and uncle had played professional baseball) through his ninth grade, but moved then to athletics, because he did not want his father to coach him. Lewis graduated from Highlands High School in 1993.

In 1999, Lewis won the US National Championships in 100 m and ran the third leg on the American 4 × 100 m relay team, which won the gold medal at the World Championships and also reached the semifinals of 100 m.
