William Donald Dennison (January 20, 1905 – May 2, 1981) was a Canadian politician who served as the 55th mayor of Toronto from 1967 to 1972. Dennison was first elected as an alderman on Toronto City Council in 1941. A member of the Co-operative Commonwealth Federation (CCF), he was elected to be the member of Provincial Parliament (MPP) for St. David from 1943 to 1945 and 1948 to 1951. He returned to municipal politics in 1953, serving as an alderman until 1958 when he was elected to the Toronto Board of Control. Dennison ran for mayor in the 1966 municipal election, defeating Phil Givens, the incumbent. Prior to entering politics, he was a school principal and teacher. As of 2022, he was the last mayor of Toronto to be a member of the Orange Order.
