James Thomas "Cool Papa" Bell was an American center fielder in Negro league baseball from 1922 to 1946. He is considered to have been one of the fastest men ever to play the game. He was elected to the Baseball Hall of Fame in 1974. He ranked 66th on a list of the greatest baseball players published by The Sporting News in 1999.

The Negro leagues were United States professional baseball leagues comprising teams of African Americans. The term may be used broadly to include professional black teams outside the leagues and it may be used narrowly for the seven relatively successful leagues beginning in 1920 that are sometimes termed "Negro Major Leagues".
