Elections to the Baseball Hall of Fame for 1947 followed yet another round of reform. The Baseball Writers' Association of America (BBWAA) continued to vote by mail but the Hall of Fame Committee had revised the procedures for that election and reduced its historical jurisdiction relative to the Old-Timers Committee. The BBWAA now considered major league players retired no more than 25 years. The reform seemed to work, as it elected four: Mickey Cochrane, Frank Frisch, Lefty Grove, and Carl Hubbell.

Gordon Stanley "Mickey" Cochrane, nicknamed "Black Mike", was an American professional baseball player, manager and coach. He played in Major League Baseball as a catcher for the Philadelphia Athletics and Detroit Tigers. Cochrane was considered one of the best catchers in baseball history and is a member of the Baseball Hall of Fame. In his first season as manager, he led the Tigers to 101 wins, which was the most for a rookie manager for 27 years.
