Fosston is a village in the Canadian province of Saskatchewan, located within the Rural Municipality of Ponass Lake No. 367 and Census Division No. 14. It is a small community with roots tied directly to the history of the families who first settled the area.
The village takes its name from Fosston, Minnesota, which was the original home of five Rustad brothers who came to the area as homesteaders. The naming reflects a common practice among early settlers of honouring the communities they left behind when establishing new homes on the Canadian prairies.
