William Lee Archer, QC (1919–2005) was a Toronto politician and lawyer.
After the death of his father the family moved to Toronto, where William found work at the age of 15 as an office boy before moving to the Imperial Bank of Canada, where he was a junior from 1937 until 1940, when he joined the Royal Canadian Naval Volunteer Reserve.
In 1963 he was appointed to the Toronto Board of Control to fill the vacancy created by Donald Summerville's death.
Archer ran for Mayor of Toronto in 1966 but was defeated by William Dennison.
In 1975, the provincial government appointed Archer chair of the Niagara Region Study Review Commission.
