Roland Edouard Gladu[a] (May 10, 1911 – July 26, 1994) was a Canadian professional baseball third baseman.

He was one of the "jumpers" who signed with the Mexican League in 1946, earning him a temporary suspension from organized baseball.

Gladu's baseball career began in 1932 at Binghamton, New York, and extended over more than 20 years as a player and manager in five countries: Canada, the United States, Mexico, Cuba, and England.

Gladu played in London in the late 1930s for a team based at West Ham Stadium.

[2] As player-manager for West Ham, he took the London circuit batting title with a .565 average in 1937, and led the team to two consecutive top-two finishes, as well as a 5-3 defeat over the touring 1936 United States Olympic baseball team.
