George Edward Winkelman (1865–1960) was a professional baseball player. He appeared in one game for the 1886 Washington Nationals of the National League. He played in the minors as late as 1895. In his only major league game, he equalled the record set by Mike Corcoran for the most wild pitches by a pitcher in their first game, with five. He pitched the first six innings of the game, giving up 11 runs on 12 hits and five walks and taking the loss. He was moved to right field to finish the game.
