William Frederick Hoeft (May 17, 1932 – March 16, 2010) was an American pitcher in Major League Baseball whose career spanned 15 seasons with the Detroit Tigers, Boston Red Sox, Baltimore Orioles, Milwaukee Braves, Chicago Cubs and San Francisco Giants.

Born in Oshkosh, Wisconsin, Hoeft threw and batted left-handed, stood 6 feet 3 inches (1.91 m) tall and weighed 180 pounds (82 kg).

He also showed occasional potential as a power hitter, once tying an American League record for consecutive home runs by a pitcher with two to begin a game.

Hoeft was traded along with Jack Fisher and Jimmie Coker from the Orioles to the Giants for Stu Miller, John Orsino and Mike McCormick on December 15, 1962.

In August, he was signed by the San Francisco Giants[4] initially as a coach and batting practice pitcher before being activated in September when playing rosters increased to 40 men.
