Situated on lowlands suitable for agriculture, it was built on part of the seigneury given in 1736 to Thomas-Jacques Taschereau. It was inhabited by colonists from the Beaupré shore and from ÎLE D'ORLÉANS. Ste-Marie is one of the oldest settlements in the Beauce region, having celebrated its 250th anniversary in 1994.

During the 19th century, Ste-Marie retained its agricultural importance, but progressively became a regional service centre as the construction of the Québec Central railway sparked the development and settlement of its hinterland. From 1880 to 1940, the wood industry was a major part of its economy. The town now has prosperous industries in the food sector and in metalworking.
