William C. "Zuke" Supplee (December 21, 1903 – July 1966)[1] was an American educator and college athlete.

[2] In 1923, Supplee was named a second-team All-American by the Associated Press, which made him the first Maryland football player to receive All-America honors.

[3][4] His performances during the team's win against Penn and its narrow loss to period powerhouse, Yale, have been cited as the main reasons for his selection.

[6] In 1924, he was selected to the All-South Atlantic and the All-Maryland football teams, the latter of which was composed of the state's best players.

One of his professors said of him, "To those who slander the American athlete as being a poor student and inferior intellect, I should like to point out Supplee as Maryland's refutation.
