Mont-Saint-Hilaire (French pronunciation: [mɔ̃ sɛ̃t‿ilɛʁ]) is a suburb of Montreal on the South Shore of southeastern Quebec, Canada, on the Richelieu River in the Regional County Municipality of La Vallée-du-Richelieu. The population as of the Canada 2021 Census was 18,859. The city is named after the Mont Saint-Hilaire.

A significant deposit of the semi-precious mineral sodalite is located near Mont-Saint-Hilaire.

Jean-Baptiste Hertel de Rouville was granted the seignory of the region in 1694.^[5] By 1745 a mountain village had been formed with the first chapel being built in 1798 near the Richelieu River. Nearly twenty years later, in 1822, a ferry operating between Beloeil and Mont-Saint-Hilaire came into service. A bridge, enabling Beloeil and St. Hilaire to be connected by rail, was built in 1848 by the St. Lawrence and Atlantic Railway. The Campbell family, owners of the mountain after that of Rouville, sold the mountain to a British officer, Brigadier-General Andrew Gault, in whose ownership it remained for 45 years. Gault then bequeathed the mountain to McGill University before his death in 1958.

In the 2021 Census of Population conducted by Statistics Canada, Mont-Saint-Hilaire had a population of 18,859 living in 7,766 of its 7,917 total private dwellings, a change of 1.5% from its 2016 population of 18,585. With a land area of 44.08 km² (17.02 sq mi), it had a population density of 427.8/km² (1,108.1/sq mi) in 2021.^[6]
