Frank James Clair (May 12, 1917 – April 3, 2005) was a coach in the Canadian Football League, nicknamed "the Professor" for his ability to recognize and develop talent.
Clair played end for the Ohio State Buckeyes, lettering in 1938, 1939, and 1940. As a receiver, he was quarterback Don Scott's favorite target. In 1941, Clair played in seven games for the Washington Redskins.
Clair found his greatest success in coaching. He was the head coach at the University at Buffalo in 1948 and 1949. During the 1950s, he coached the Toronto Argonauts to two Grey Cups in 1950 and 1952.
In 1956, he joined the Ottawa Rough Riders. As coach, Clair led them to Grey Cup Championships in 1960, 1968 and 1969. While he was general manager, the team won Grey Cups in 1973 and 1976. After he was let go in 1978, the team won no more Grey Cups. He was inducted into the Canadian Football Hall of Fame in 1981.
Frank Clair Stadium at Lansdowne Park was renamed in his honor in 1993.
