HMCS Porte de la Reine was a Porte-class gate vessel of the Royal Canadian Navy.

Though the class were designed to operate the gates in anti-submarine booms, there was little need for this during the Cold War and Porte de la Reine was placed in reserve in 1957.

The class was reactivated in the mid-1960s and used as training vessels for personnel of the Canadian Forces Naval Reserve.

Porte de la Reine was based at Esquimalt, British Columbia until being paid off on 19 December 1996 and disposed of.

A notice in the Skagit Valley Herald on Wednesday, 20 March 2013 announced a "Notification of Intent to Obtain Custody".
