Saint-Basile-le-Grand (French pronunciation: [sɛ̃ bazil lə ɡʁɑ̃]) is a city located in La Vallée-du-Richelieu Regional County Municipality in southwestern Quebec, Canada.

Its territory, the majority of which is still agricultural, occupies an area of 35.84 km2 between the Richelieu River and Mont Saint-Bruno.

Here is a quote from Mr. Moreau who went to the stone house of Basile Daigneault to hold his meeting: "Built [the house] on the land with Mr. Basile Daigneault as a neighbor on both sides, on Rang des Vingt-Quatre, /…/, it was found that the majority of the freeholder inhabitants wanted to buy it.

This was in the sights of the municipality in the early 2000s, when a regulation prohibiting fortifications (bulletproof glass, maximum exterior cameras and limitation of the height of fences) was adopted by the city council.

Local bus service is provided by the Exo de la Vallée du Richelieu sector.
