Tadoussac is a village in Quebec, Canada, at the confluence of the Saguenay and Saint Lawrencerivers. Established at an Innu settlement, it was France's first trading post on the mainland of New France. By the 17th century it became an important trading post and was the oldest continuously inhabited European settlement in Canada, and the oldest surviving French settlement in the Americas.
The indigenous Innu called the place Totouskak (plural for totouswk or totochak) meaning "bosom", probably in reference to the two round and sandy hills located on the west side of the village. According to other interpretations, it could also mean "place of lobsters", or "place where the ice is broken" (from the Innu shashuko).
