Thomas Francis "King" Clancy (December 2, 1872 – September 28, 1938) was a Canadian football player and coach. He was originally a baseball player before becoming a football player in 1894. He was the coach of the Ottawa Rough Riders from 1904 to 1911, 1913, and 1921 to 1922 (and an assistant in 1919). Clancy was known as "The original King", since his son, Frank Clancy was known as King Clancy.
