Saint-Louis-de-Gonzague-du-Cap-Tourmente (French pronunciation: [sɛ̃ lwi də ɡɔ̃zaɡ dy kap tuʁmɑ̃t]) is a parish municipality in Quebec, Canada.

[1] Saint-Louis-de-Gonzague-du-Cap-Tourmente is a small enclave within the municipality of Saint-Joachim, at the foot of Cape Tourmente, and east of Sainte-Anne-de-Beaupré, in the regional county municipality of La Côte-de-Beaupré in the region of Capitale-Nationale.

Located near the provincial capital of Quebec City, it is part of the Communauté métropolitaine de Québec.

Named for Saint Aloysius Gonzaga and Cap Tourmente, a stormy promontory named by Samuel de Champlain, the municipality was set up in 1917 by a law that detached certain buildings and lands belonging to the Séminaire de Québec from the parish of Saint-Joachim in order to avoid paying municipal taxes and fees.

At that time, it had an area of several square kilometres, including farmland; however, the law specified that if the Séminaire sold any of its property, it would revert to Saint-Joachim.
