The Knife River is a tributary of the Snake River in east-central Minnesota in the United States. It is one of three streams in Minnesota with this name. Its name is a translation from the Dakota "Isaanti". Knife Lake and Santee Sioux are named after this river. In turn Isanti County is named after the Santee Sioux.

Only one lake is associated with the Knife River: Knife Lake. No major tributaries are associated with the Knife River. However, the river served as an important trade route for the Dakota, the Ojibwe, and the Voyageurs, connecting the Mississippi River (via Mille Lacs Lake) to the St. Croix River.
