LeRoy Walter Majtyka (born June 1, 1939) is an American former infielder and manager in minor league baseball.

He threw and batted right-handed, stood 5 ft 11 in (1.80 m) tall and weighed 170 lb (77 kg) during his active career.

Majtyka managed for 27 years in the minor leagues, beginning with the Cardinals' farm system in 1968, and also working with the Cincinnati Reds, Detroit Tigers, Braves and Philadelphia Phillies.

His 1973 St. Petersburg Cardinals won the Florida State League championship and Majtyka was cited as Manager of the Year in the Eastern League for leading the 1976 Trois-Rivières Aigles to a division title.

His three seasons (1988–1990) as a coach with the Braves were the only interruption to a minor-league managerial career (1968–1987; 1991–1997) in which his teams won 1,832 games and lost 1,747, for a winning percentage of .512.
