Lewis Aloysius Malone (March 13, 1897 – February 17, 1972) was an American professional baseball infielder. He played in Major League Baseball (MLB) from 1915 to 1919 for the Philadelphia Athletics and Brooklyn Robins. In 1918 Malone's career was interrupted while he served in World War I. After returning from World War I, Malone continued to play in the Minors until 1929. His first (and last) major league home run came in 1915, at the age of 18. He is believed to be the youngest major leaguer ever to hit his last home run.
