Joseph Francis Gavan Power (13 June 1918 – 1973) was a Liberal party member of the House of Commons of Canada.

He became a prisoner of war of the Japanese Imperial Army when Hong Kong fell on Christmas Day of 1941.

He like other allied prisoners of war suffered from the inhumane treatment administered by the Japanese, and bore the scars for the remainder of his life.

He was first elected at the Quebec South riding in a 26 September 1955 by-election succeeding his father, Charles Gavan Power, who was appointed to the Senate.
