Earl Oliver Whitehill (February 7, 1899 – October 22, 1954) was an American Major League Baseball pitcher.

He played for the Detroit Tigers for the most significant portion of his career (1923–1932), and later with the Washington Senators (1933–1936), Cleveland Indians (1937–38), and the Chicago Cubs (1939).

In his early years with Detroit, Whitehill was part of a starting rotation that included Hooks Dauss, Dutch Leonard, and Lil Stoner.

Whitehill, one of the top pitchers of the Roaring Twenties, had a celebrity marriage to Violet Geissinger.

With Washington that year, he saw his first (and last) postseason action, when the Senators were defeated by the New York Giants in 5 games.

After serving as a coach for the Indians, the Philadelphia Phillies, and in the International League in the early 1940s, he became a sales representative for the A. G. Spalding sporting goods firm.

Whitehill died from injuries sustained in an automobile accident in Omaha, Nebraska, at the age of 55.
