The Poplar River is a tributary of the Missouri River, approximately 167 mi (269 km) long in Saskatchewan in Canada and Montana in the United States.
It rises in several forks on the plains of southern Saskatchewan. The western fork rises near Killdeer, Saskatchewan and flows southeast, into northeastern Montana, past Richland and across Daniels County. The middle fork rises northwest of Rockglen, Saskatchewan and flows southeast, into northeastern Montana and passes west of Scobey. The two forks unite in the northern Fort Peck Indian Reservation. The combined fork flows SE, then SSW, and joins the Missouri near Poplar.
Along with the Milk River and Big Muddy Creek, it is one of three waterways in Canada that drain into the Gulf of Mexico.
The Poplar River has also been known as: Lost Child Creek and Middle Fork Poplar River.[1]
