Fred Thomas (December 26, 1923 – May 20, 1981) was a Canadian multi-sport professional athlete. He played on semi-professional or professional teams in basketball, baseball, and Canadian football. He was a standout on his college basketball team and is known as one of Canada's finest basketball players. A 2019 profile by TVOntario described Thomas as "the greatest Canadian athlete you've never heard of". He would likely have been more well-known had blacks not been denied opportunities to compete in major professional sports leagues in the 1940s and 1950s.
