Thomas Francis "King" Clancy (December 2, 1872 – September 28, 1938) was a Canadian football player and coach.

Clancy was a noted baseball player in the late 1800s along with his two brothers, Michael and William.

He learned football from his coach at Ottawa College, Father Michael Fallon.

He led his team to a win in the Dominion Championship of Queen's University (8 to 7) in his first season.

He would later visit the players and give them "pep" talks at practice.
