Marvin Julian Miller (April 14, 1917 – November 27, 2012) was an American baseball executive who served as the executive director of the Major League Baseball Players Association (MLBPA) from 1966 to 1982. Under Miller's direction, the players' union was transformed into one of the strongest unions in the United States. In 1992, Red Barber said, "Marvin Miller, along with Babe Ruth and Jackie Robinson, is one of the two or three most important men in baseball history." Miller was selected to the National Baseball Hall of Fame in December 2019, for induction in 2020.
