Ernest William Rudolph (February 13, 1909 – January 13, 2003) was a Major League Baseball pitcher who appeared in seven games, all in relief, for the Brooklyn Dodgers in 1945.

Rudolph is one of many ballplayers who only appeared in the major leagues during World War II.

His lone major league win came eleven days later in a 6–5 victory over the Chicago Cubs at Ebbets Field.

Rudolph is the only player from the short-lived Twin Ports League to ever play in the majors.
