John Michael William Curphey Forrestall (September 23, 1932 – June 8, 2006) was a Canadian politician.

During the Brian Mulroney government, Forrestall served as a parliamentary secretary to a succession of ministers until he was defeated in what was by then the riding of Dartmouth in the 1988 federal election.

Forrestall was active on a number of causes, including benefits for Canadian Merchant Navy veterans and the protection of lighthouses.

In 2000, he introduced a Private Members Bill in the Senate Heritage Lighthouse Protection Act, a bill which was also supported by Senator Pat Carney who championed it after Forrestall's death and which is close to passing in the House of Commons in 2007.

[2] Forrestall died on June 8, 2006, at age 73;[3] he had been admitted to a Halifax-area hospital with serious breathing problems five days earlier.
