The Medicine River is a medium-sized river in central Alberta. It begins at the outlet of Medicine Lake, north of Rocky Mountain House. The Medicine River initially travels through the Rocky Mountain House Grazing Reserve, a protected area with over 15,000 acres (61 km²) of land set aside for cattle grazing and recreation. The river flows southwest, taking on a number of creeks before passing Eckville. The Medicine River joins the Red Deer River north of Innisfail, downstream of the Dickson Dam, at the Medicine Flats.
