Mount Royal is a large intrusive rock hill or small mountain in the city of Montreal, immediately west of Downtown Montreal, Quebec, Canada. The best-known hypothesis for the origin of the name Montreal is that the name is taken from Mount Royal.
The hill is part of the Monteregian Hills situated between the Laurentians and the Appalachian Mountains. It gave its Latin name, Mons Regius, to the Monteregian chain. The hill consists of three peaks: Colline de la Croix (or Mont Royal proper) at 233 m (764 ft), Colline d’Outremont (or Mount Murray, in the borough of Outremont) at 211 m (692 ft), and Westmount Summit at 201 m (659 ft) elevation above mean sea level.
