The Royal Canadian Navy (RCN) (French: Marine royale canadienne) is the naval force of Canada. The RCN is one of three environmental commands within the unified Canadian Forces. As of 2012^[update], operating 33 warships and several auxiliary vessels, the Royal Canadian Navy consists of 8,500 Regular Force and 5,100 Primary Reserve sailors, supported by 5,300 civilians. Vice-Admiral Paul Maddison, OMM MSM CD, is the current Commander of the Royal Canadian Navy and Chief of the Naval Staff.

Founded in 1910 as the Naval Service of Canada and given royal sanction in 1911, the RCN was placed under the Department of National Defence in 1923, and amalgamated with the Royal Canadian Air Force and the Canadian Army to form the unified Canadian Forces in 1968, where it was known as the Maritime Command until 2011. Over the course of its history, the RCN served in the First and Second World Wars, the Korean War, the First Gulf War, the Afghanistan War and numerous United Nations peacekeeping missions and NATO operations.
