Sainte-Martine is a municipality in Beauharnois-Salaberry Regional County Municipality in the Montérégie region of Quebec, Canada. The population as of the 2021 Canadian census was 5,664. The municipality is made up of a large northern section and a small unattached southern area that was known as the municipality of Saint-Paul-de-Châteauguay until its merger with Sainte-Martine on September 9, 1999.
Sainte-Martine is named in honor of Martina of Rome, martyred in 226. Being already settled and recognize as Sainte-Martine for many years, the status of the municipality was officialized on July 1, 1855, as the parish municipality of Sainte-Martine.
The municipality lost a section of its territory in 1885 for the creation of the parish of Très-Saint-Sacrement. It also lost a sizeable part in 1937 when Saint-Paul-de-Châteauguay split from Saint-Martine to become its own municipality, but it was eventually reattached to Sainte-Martine in 1999.[3]
In addition to the namesake main population centre, the following locations reside within the municipality's boundaries:
