former city, Québec region, southern Quebec province, Canada. In 2002 it was incorporated into Quebec city, becoming a borough of the enlarged city. Sainte-Foy borough is situated on the north bank of the St. Lawrence River, opposite the mouth of the Saint-Charles River, in the southwestern part of Quebec city. Originally named for a village in France, the settlement was called Notre-Dame-de-Foy after a canonical parish was formed there in 1698; however, the shorter name prevailed. Sainte-Foy was the scene of a French victory over the British in 1760, a year after the fall of Quebec, but the arrival of British naval forces forced the French to withdraw to Montreal. It was incorporated as a city in 1955, retaining that status until its amalgamation into Quebec city in 2002.

Although Sainte-Foy is chiefly a residential district of Quebec city, there has been some zoned industrial development. Industrial growth was rapid after 1950 because of Sainte-Foy's central location on both national railways and several major highways and its proximity to Quebec's airport and a major regional bridge spanning the St. Lawrence River. The campus of Laval University (founded 1663 in Quebec city; rechartered 1852) occupies the borough's eastern area. Sainte-Foy is also the site of Marymount and Saint-Lawrence colleges and a provincial aquarium.
