Rocky Boy Indian Reservation

Rocky Boy's Indian Reservation is one of seven Native American reservations in the U.S. state of Montana. Established by an act of Congress on September 7, 1916, it was named after Ahsiniiwin, the chief of the Chippewa band, who had died a few months earlier. It was established for landless Chippewa Indians in the American West, but within a short period of time many Cree and Métis were also settled there. Today the Cree outnumber the Chippewa on the reservation. The Bureau of Indian Affairs recognizes it as the Chippewa Cree Reservation.

The reservation is located in Hill and Chouteau counties in north central Montana, about 40 miles from the Canada–U.S. border. It has a total land area of 171.4 square miles, which includes extensive off-reservation trust lands. The reservation is reported to have 3,323 enrolled members, 55% of the total 6,177 enrolled members in the tribe.
