The Royal Canadian Mounted Police (RCMP) (French: Gendarmerie royale du Canada (GRC), literally ‘Royal Gendarmerie of Canada'; colloquially known as The Mounties, and internally as ‘The Force') is the national police force of Canada, and one of the most recognized of its kind in the world. It is unique in the world as a national, federal, provincial and municipal policing body. The RCMP provides policing services to all of Canada at a federal level, and also on a contract basis to the three territories, eight of Canada's provinces (the RCMP does not provide provincial or municipal policing in either Ontario or Quebec), more than 190 municipalities, 184 aboriginal communities, and three international airports.

The RCMP was formed in 1920 by the merger of the Royal Northwest Mounted Police (RNWMP, founded 1873) with the Dominion Police (founded 1868). The former was originally named the North-West Mounted Police (NWMP), and was given the Royal prefix by King Edward VII in 1904. Much of the present-day organization's symbolism has been inherited from its days as the NWMP, including the distinctive Red Serge uniform, paramilitary heritage, and mythos as a frontier force. The RCMP/GRC wording is specifically protected under the Trade-marks Act.

As the national police force of Canada, the Royal Canadian Mounted Police is primarily responsible for enforcing federal laws throughout Canada, while general law and order including the enforcement of the Criminal Code and applicable provincial legislation is constitutionally the responsibility of the provinces and territories. This responsibility is sometimes further delegated to municipalities which can form their own municipal police departments. This is common in the largest cities.
