St. Regis, in brief

Wikipedia doesn’t have a history of St. Regis yet. The photos, dates and memories neighbors add here are how it gets written.

St. Regis or Saint Regis is an unincorporated community and census-designated place (CDP) in Mineral County, Montana. The population was 313 at the time of the 2020 census. Pierre-Jean De Smet travelled extensively in this area of Montana. He named the river, after which the town takes its name, after a fellow Jesuit priest. The post office opened in 1896. The Northern Pacific Railway built a railroad through the town in the early 1900's, boosting the economy.

Its first post office opened in 1896. Its population held steady between the last two censuses: 319 in 2010, 313 in 2020.
