Jacques Flynn PC OC QC (August 22, 1915 – September 21, 2000) was a Canadian lawyer and federal politician, serving in both the House of Commons and Senate.
A Progressive Conservative, Flynn ran unsuccessfully to represent the riding of Quebec South in the House of Commons in the 1957 election; he came second to the Liberal incumbent, Frank Power.
He narrowly defeated Power in a rematch in Quebec South in the 1958 election when John Diefenbaker led the PC Party to a landslide victory.
In December 1961, Prime Minister Diefenbaker brought Flynn into the Cabinet of Canada as Minister of Mines and Technical Surveys, a position he held until losing his seat to Liberal challenger Jean-Charles Cantin in the 1962 election that reduced the Conservatives to a minority government.
With the defeat of the Clark government to Pierre Trudeau's Liberals in the 1980 election, Flynn returned to the position of Leader of the Opposition in the Senate.
