Demographics
According to the United States Census Bureau, St. Mary was listed as a CDP for the 2020 census. The census recorded a resident population, but the precise figure is not provided here. The community’s population is small and predominantly of Native American heritage, reflecting its location within the Blackfeet Reservation.
History
The region surrounding St. Mary was traditionally inhabited by the Blackfeet (Niitsítapi) people. European‑American exploration of the area began in the mid‑19th century, and the St. Mary River was named by early trappers and missionaries. The community that later developed near the river adopted the same name. Its proximity to the eastern entrance of Glacier National Park has made it a gateway for tourism and park‑related services.
Economy and Services
St. Mary’s economy is largely tied to tourism associated with Glacier National Park, including lodging, guiding services, and seasonal employment. Essential services such as postal delivery and basic retail are available within the community or in nearby towns such as Browning, the administrative center of the Blackfeet Reservation.
Education
Students in St. Mary generally attend schools operated by the Browning Public Schools district, which serves the Blackfeet Reservation.
