Sainte-Thérèse (French pronunciation: [sɛ̃t teʁɛz]) is an off-island suburb northwest of Montreal, in southwestern Quebec, Canada, in the Thérèse-De Blainville Regional County Municipality.

On June 1, 1849, the Village of Sainte-Thérèse was created following a request from Louis Marteau, Paul Filiatrault and Joseph-Benjamin Lachaîne to the Terrebonne County Parish Council.

Before the General Motors plant arrival in 1966 (in neighbouring Ste-Thérèse Ouest, now Boisbriand), Agricultural and equipment company Machineries Dion was the biggest employer of the region.

Steel foundry, state of the art workshop, cast iron parts and ingenious thinking made Machineries Dion a leader in the equipment market.

Inventors of the first pull-type forage harvester in the world with macerating rolls for hay and corn (invented in the 1970s, which would later become important in a Claas vs John Deere proprietary patent lawsuit).

After the initial success, more divisions would emerge; concrete silos, maple syrup extraction equipment and agricultural technology development soon followed.
