Chicoutimi is the most populous borough (arrondissement) of the city of Saguenay in Quebec, Canada. Chicoutimi was founded as a city in 1842 at the confluence of the Saguenay and Chicoutimi rivers. The name Chicoutimi means the end of the deep water in the Montagnais language. During the 20th century, it became the main administrative and commercial centre of the Saguenay–Lac-Saint-Jean region and the heart of the 5th largest urban area of Quebec. It is home to the University of Quebec in Chicoutimi (Université du Québec à Chicoutimi).
What was ultimately to become the centre of the borough of Chicoutimi was first settled in 1676 as a French trading post in the fur trade. At that time, the Saguenay and the Chicoutimi rivers had been used as waterways by the Montagnais tribes for centuries. The name Chicoutimi means the end of the deep water in the Montagnais language. Chicoutimi trading post was in operation until 1782. The city of Chicoutimi was officially incorporated as a municipality in 1845 by the Métis timber contractor Peter McLeod who built a sawmill there in 1842. It became the seat of the Chicoutimi County in 1855 and the seat Roman Catholic Diocese of Chicoutimi in 1878.
