William Aloysius Cunningham (July 30, 1894 – September 26, 1953), was a Major League Baseball player who played outfielder from 1921-1924. He would play for the Boston Braves and New York Giants. Cunningham's two-run single in the second inning of the 1922 World Series' final game sparked the Giants to a 5–3 victory over the New York Yankees at the Polo Grounds and the championship. A year later, a Cunningham hit in the final game of the 1923 World Series put the Giants on top, but the Yankees rallied to win it.
