The Peace River (French: rivière de la Paix ) is a 1,923-kilometre-long (1,195 mi) river in Canada that originates in the Rocky Mountains of northern British Columbia and flows to the northeast through northern Alberta . The Peace River joins the Athabasca River in the Peace-Athabasca Delta to form the Slave River , a tributary of the Mackenzie River . The Finlay River , the main headwater of the Peace River, is regarded as the ultimate source of the Mackenzie River. The combined Finlay–Peace–Slave–Mackenzie river system is the 13th longest river system in the world .
24-667: The regions along the river are the traditional home of the Dane-zaa people , called the Beaver by the Europeans. The fur trader Peter Pond is believed to have visited the river in 1785. In 1788 Charles Boyer of the North West Company established a fur trading post at the river's junction with the Boyer River . In 1792 and 1793, the explorer Alexander Mackenzie travelled up the river to

Prophet River First Nation (PRFN) uses Dene Tsaa ; and the West Moberly First Nations (WMFNs) use Dunne-za or Dunne Za . Where other spellings are used in citations, such as Dunne-Za (e.g., Ridington 1988), they are kept intact and are synonymous with Dane-zaa. The historic usual English term Beaver

A large man-made lake, Williston Lake , has been formed on the upper reaches by the construction of the W. A. C. Bennett Dam for hydroelectric power generation. Prior to its flooding, the confluence of the Finlay and Parsnip Rivers at Finlay Forks was distinct. A half mile east of that location were

The Peace River, before and after its new name, marked a boundary zone, where groups met for trade, celebration, and settling of disputes. A post journal of 1799–1800 mentions people trading at the post who can be identified as the ancestors of members of the former Fort St John Band, now the Doig River and Blueberry River First Nations. Doig oral history confirms that

By the time the Hudson's Bay Company took over the North West Company in 1823, bison were scarce. Traditionally, Dane-zaa has followed
