The Kazan River (Inuktitut Harvaqtuuq,[3] Inuktitut syllabics ᓴᕐᕙᖅᑑᖅ;[4] meaning "strong rapids",[5] "the big drift"[3] or "place of much fast flowing water"[4]), is a Canadian Heritage River located in Nunavut, Canada.

The name was apparently changed to Kazan in the late 19th century due to the influence of Order of Mary Immaculate missionaries.

The abundance of wildlife along and close to the river attracted both the Caribou Inuit and the Chipewyan Sayisi Dene for about 5,000 years.

In the 18th century, Dene use of the area declined and Caribou Inuit, especially the Harvaqtuurmiut ("people of the Harvaqtuuq") and Ihalmiut bands, began to live along the river year round.

Other wildlife that may be observed in the area include muskox, wolverine, peregrine falcon and many species of fish.
