Paul Gregory Williams (born August 7, 1956) is a Canadian retired long-distance runner, who represented his native country at three consecutive Summer Olympics, starting in 1984.
Starting his career in the late 1960s as an age-class runner in the Beach community in Toronto's east end, he competed regularly in OFSSA track and cross-country competitions (from 1970–75) for Riverdale Collegiate with his older brother Don, and went on to a stellar athletics career at both the University of Guelph and the University of Toronto.
Williams matured quickly as a young distance runner, especially under the influence of two powerful role models in the sport.
One was Bruce Kidd, Canada's premier distance runner through the 1960s and the gold medallist over 6 miles at the 1962 Commonwealth Games.
