Cletus Elwood "Boots" Poffenberger (July 1, 1915 – September 1, 1999) was a Major League Baseball pitcher for the Detroit Tigers (1937–1939) and Brooklyn Dodgers (1939). His major league career ended due to his erratic behavior, and he played in minor league teams Nashville Vols (1940) and San Diego Padres (1942), before joining the United States Marine Corps during World War II. He returned to the Padres briefly in 1946.
