The Hero-class patrol vessels, previously the Mid-Shore Patrol Vessel Project, is a series of nine patrol vessels constructed by Halifax Shipyards for the Canadian Coast Guard. Based on the Dutch Damen Stan 4207 patrol vessel, construction began in 2011 and the first vessel entered service in 2012. The vessels are assigned to the Atlantic and Pacific coasts of Canada, used for coastal patrol duties.

A patrol boat is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine, estuarine, or river environments.
