Nipawin is a town in Saskatchewan, Canada, on the Saskatchewan River portion of Tobin Lake. The town lies between Codette Lake, created by the Francois-Finlay Dam and Tobin Lake, created by the E.B. Campbell Dam built in 1963, renamed from Squaw Rapids. The construction of Francois-Finlay Dam earned Nipawin the nickname the "Town of Two Lakes".

The Saskatchewan River is a major river in Canada. It stretches about 550 kilometres (340 mi) from where it is formed by the joining of the North Saskatchewan River and South Saskatchewan River just east of Prince Albert, Saskatchewan, to Lake Winnipeg. It flows roughly eastward across Saskatchewan and Manitoba to empty into Lake Winnipeg. Through its tributaries the North Saskatchewan and South Saskatchewan, its watershed encompasses much of the prairie regions of Canada, stretching westward to the Rocky Mountains in Alberta and north-western Montana in the United States.
