Herbert Jefferis Pennock (February 10, 1894 – January 30, 1948) was an American professional baseball pitcher and front-office executive. He played in Major League Baseball from 1912 through 1933, and is best known for his time spent with the star-studded New York Yankee teams of the mid to late 1920s and early 1930s.
Pennock was signed by the Philadelphia Athletics in 1912, but was used sparingly by the Athletics and the Boston Red Sox, who bought his contract in 1915. After returning from military service in 1919, Pennock became a regular contributor for the Red Sox. The Yankees acquired Pennock after the 1922 season, and he served as a key member of the pitching staff as the Yankees won four World Series championships. After retiring as a player, Pennock served as a coach and farm system director for the Red Sox, and as general manager of the Philadelphia Phillies.
Pennock was regarded as one of the greatest left-handed pitchers in baseball history. He died of a cerebral hemorrhage in 1948, and was inducted into the National Baseball Hall of Fame later that year.
