Saint-Marc-sur-Richelieu (French pronunciation: [sɛ̃ maʁk syʁ ʁiʃ(ə)ljø], lit. 'Saint-Marc on Richelieu') is a municipality in southwestern 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 2,245.

In its origin, the municipality was simply named: Saint-Marc. In 1921, the municipality lost an important part of its territory for the creation of the new municipality of Saint-Amable. In 1980, the municipality of Saint-Marc changed its name to the current name of Saint-Marc-sur-Richelieu.
On October 10, 2012, the municipality was reportedly the epicenter of an earthquake measuring 4.5 on the Richter scale.

The Richelieu River forms the eastern boundary of the municipality as it flows northwards.
