James Edgar Lennox (November 3, 1883 – October 26, 1939) was an American professional baseball third baseman. He played in Major League Baseball (MLB) for the Philadelphia Athletics, Brooklyn Superbas, Chicago Cubs, and Pittsburgh Rebels. While playing for the Rebels in 1914, Lennox hit for the cycle on May 6, becoming the only Federal League player to do so. He also hit pinch-hit home runs in consecutive games on June 10 and 11, a feat that was not accomplished again until Victor Martinez of the Detroit Tigers did so against the Miami Marlins on April 4 and 5, 2016.
