Cyril William "Bill" Doody (February 26, 1931 – December 27, 2005) was a member of the Senate of Canada representing Newfoundland and Labrador. Doody was active in provincial politics and was first elected to the Newfoundland and Labrador House of Assembly in 1971 as a member of the Progressive Conservative Party of Newfoundland and Labrador.
Doody was born in St. John's and was educated at Saint Bonaventure's College. In 1971, he resigned from his position as managing director of a supermarket to run for political office. He became Minister of Mines, Agriculture and Resources when Frank Moores formed his government in 1972. In 1975, Doody became the province's finance minister. After Moores resigned, Doody was widely expected to succeed him but was defeated by Brian Peckford in the March 17, 1979 PC leadership convention. Premier Peckford appointed Doody Minister of Mines and Energy. He was to retire from the Senate in February 2006, but died almost two months prior to his scheduled retirement.
