Buffalo Narrows (Plains Cree: ᒧᐢᑐᓱ ᐘᐹᓯᕽ, romanized: mostoso-wapâsihk) is a northern village in Saskatchewan, Canada.

Buffalo Narrows or Détroit du Boeuf as it was called in French was founded in the early 20th century as trapping, mink ranching and fishing settlement by Scandinavian traders.

John Macoun, who was travelling the fur trade route from Methye Portage to Lac Île-à-la-Crosse visited the "Narrows" in September 1875.

He described his visit to this old community in the following lines: "After sunrise, a headwind sprang up with which we battled all day and reached the "Narrows," that connect Buffalo and Clearwater lakes, before dark.

"Chipewyan House" is situated at the eastern end of the "Narrows," and at the head of Clearwater Lake.

On 30 January 1969, the community was the site of the killing of the Pedersen family, and their friend John Herman.

Formerly Crown land, the recreation area was transferred to the northern village of Buffalo Narrows in 2003.
