Chicoutimi (/ʃɪˈkuːtɪmi/ shih-KOO-tim-ee, French: [ʃikutimi]) is the most populous borough (arrondissement) of the city of Saguenay in Quebec, Canada.

In 2002 it merged into the new city of Saguenay and forms the heart of the 5th-largest urban area of the province of Quebec.

At that time, the Saguenay and the Chicoutimi rivers had been used as waterways by the Montagnais tribes for centuries.

The city of Chicoutimi was officially incorporated in 1845 as a municipality by Peter McLeod, a Métis timber contractor who built a sawmill there in 1842.

During the summer of 1996, a record rainfall in the region caused major flooding in the downtown, as well as outlying areas.

It is the geographical centre of the city of Saguenay; the Jonquière and La Baie boroughs adjoin on the west and east sides.

The landscape of Chicoutimi consists of hills, valleys and plains, with the terrain becoming steeper near the Saguenay River.

Mount Valin at 3,215 feet (980 metres) is the tallest mountain of the region, and overlooks Chicoutimi 30 kilometres (19 miles) north-east.
