Myril Oliver Hoag (March 9, 1908 – July 28, 1971) was an American professional baseball player.

An outfielder, Hoag played in Major League Baseball (MLB) for the New York Yankees, St. Louis Browns, Chicago White Sox, and Cleveland Indians between 1931 and 1945 and was on the winning team in three World Series.

Hoag missed some of the 1936 season due to having a blood clot on the brain, the result of an outfield collision with teammate Joe DiMaggio.

In 1939, Hoag made the American League All-Star team with the St. Louis Browns after the Yankees traded him there for Oral Hildebrand and Buster Mills.

On June 6, 1934, he collected six hits in one game in a 15–3 rout against the Red Sox, and was the last New York Yankee to accomplish this feat until Gerald Williams did so against the Baltimore Orioles on May 1, 1996.
