Tadoussac is a village in Quebec, Canada, at the confluence of the Saint Lawrence and Saguenay rivers. It was France's first trading piston the mainland of New France and an important trading post in the seventeenth century, making it the oldest continuously inhabited European settlement in Quebec, and the oldest surviving French settlement in the Americas.
The indigenous Montagnais called the place Totouskak (plural for totouswk or totochak) meaning "udders", 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 Montagnais shashuko).
Although located in Montagnais territory, it was frequented by the Mi'kmaq people in the second half of the 16th century, who called it Gtatosag ("among the rocks"). Alternate spellings of Tadoussac over the centuries included Tadousac (17th and 18th centuries), Tadoussak, and Thadoyzeau
