Mount Royal (French: Mont-Royal) is a federal electoral district in Quebec, Canada, that has been represented in the House of Commons of Canada since 1925. Its population in 2006 was 98,888.

The riding is among the strongest Liberal ridings in the country. Réal Caouette, long-time leader of the Social Credit Party in Quebec, once said that a mailbox could win the Liberal nomination in Mount Royal and still win election just because it was red (the traditional colour of the Liberal Party). The Liberals have held the riding continuously since 1940, and have only been seriously threatened three times since then—in 1958, 1984 and 2011.

Its best-known MP is former Prime Minister Pierre Trudeau, who represented the riding from 1965 to 1984. Its current MP, Anthony Housefather, was elected on October 19, 2015, garnering 50.4% of the vote, and was profiled as one of 10 rookie MPs to watch in the new parliament.

Once the English name of this riding was eliminated in the 2012 electoral redistribution but reversed by the Riding Name Change Act, 2014.

The riding has a large Jewish population, the second largest in Canada—36.3 percent. Mount Royal and Thornhill in Ontario are the only two districts in Canada where Judaism is the most commonly practised religion.

The district includes the City of Côte Saint-Luc, the Towns of Mount Royal and Hampstead, the neighbourhood of Snowdon and the western part of the neighbourhood of Côte-des-Neiges in the City of Montreal.
