Saint-Lin–Laurentides (French pronunciation: [sɛ̃ lɛ̃ lɔʁɑ̃tid]) is a small city located in the Montcalm Regional County Municipality of Quebec, Canada. Its official name uses an en dash; however, the city's own website uses the two-hyphen version of its name: Saint-Lin-Laurentides. In the Canada 2021 Census its population was 24,030.

Saint-Lin was the birthplace of former Canadian Prime Minister Wilfrid Laurier, whose paternal home is now a National Historic Site of Canada.

Saint-Lin–Laurentides was formed on 1 March 2000, when the Municipality of Saint-Lin and the Town of Laurentides were merged.

Saint-Lin was first settled in 1807 when pioneers from Saint-Pierre-du-Portage (now L'Assomption) arrived. In 1828, the Saint-Lin-de-Lachenaie Parish was founded. In 1845, the Parish Municipality of Saint-Lin was established, but was abolished 2 years later in 1847 when it was absorbed into the county municipality. That same year, its post office opened. In 1855, the municipality was reestablished as Saint-Lin-de-Lachenaye, with Carolus Laurier, father of Sir Wilfrid Laurier, as first mayor.

Laurentides was originally the Village Municipality of Saint-Lin, which became an incorporate entity in 1856. In 1883, it changed name and statutes and became the Town of Laurentides. Also that year, the local post office opened.

In the 2021 Census of Population conducted by Statistics Canada, Saint-Lin—Laurentides had a population of 24,030 living in 9,289 of its 9,615 total private dwellings, a change of 15.6% from its 2016 population of 20,786. With a land area of 118.29 km (45.67 sq mi), it had a population density of 203.1/km (526.1/sq mi) in 2021.
