Prairie County was created by the Montana Legislature in 1915 out of parts of Custer, Dawson, and Fallon Counties.
The name was selected in a contest and reflects the predominant landscape of the region.
The county seat is Terry, MT.
The county was the site of the Custer Creek train wreck in 1938 that killed 47 people and injured an additional 75.

If you have any Prairie County information to add to this website, please email me.
Histories, biographies, births, deaths, marriages, and more are needed to make this a great resource for researchers.
Thanks, Shirley
