Milk River is a town in the province of Alberta, Canada, located on and named after the Milk River, which flows immediately to its south. It is 70 kilometres south of Alberta's fourth largest city Lethbridge and 16 km from the Canada-US border. Its population is 879 (2001). It is primarily a service centre for the many farms and cattle ranches which surround it.

Milk River has five Christian churches and two schools, Milk River Elementary School and Erle Rivers High School. It also offers its residents a nine-hole golf course, a curling rink, a swimming pool, and a skateboard park.

The Milk River area was first settled around the beginning of the 20th century. Milk River was incorporated as a village on 1916 July 31, and on 1956 March 15, it was declared a town. Its motto, "Under Eight Flags", comes about because, over the history of the area, it has been under the flags of seven governments and the Hudson's Bay Company. Including HBC (1818-1869), the eight flags are France (1682-1762), the Spanish Empire (1762-1800), the French Republic (1800-1803), the United States (1803-1818), the British Empire (1869-1945), the Canadian Red Ensign (1945-1965), and the current Canadian Maple Leaf (1965-present).

Writing-on-Stone Provincial Park, a significant Canadian heritage site, is located 44 kilometres east of the town.
