William Thomas Harmon (March 21, 1884 – April 21, 1959) was an American college football, college basketball, and college baseball, and track and field coach, athletics administrator, and educator. He served as the head football coach at St. Mary's College in St. Mary, Kentucky from 1907 to 1909 and two stints as the head football coach at Illinois College in Jacksonville, Illinois, from 1910 to 1917 and 1919 to 1931.

Harmon attended Illinois College, where he was captain of the football, basketball, baseball, and track and field teams before graduating in 1907. He was appointed head coach and athletic director at his alma mater, Illinois College, in 1910. Harmon's tenure as coach at Illinois College was interrupted by World War I, during which he served as a captain in the United States Army at Camp Grant near Rockford, Illinois. He was succeeded in 1917 as head football coach at Illinois College by his brother, Robert E. Harmon. After the war, in 1919, Harmon returned to coach at the college. He left Illinois College in 1932, and became commissioner of the Illinois Intercollegiate Athletic Conference (IIAC)—later known as the Interstate Intercollegiate Athletic Conference. From 1934 to 1941, Harmon served as managing officer of the Illinois State School for Boys in St. Charles, Illinois.
