Culbertson is a town in Roosevelt County, Montana, United States.

The town was named after Major Alexander Culbertson, former head of the American Fur Company's Fort Union, 23 miles (37 km) to the east.

[4] The settlement of Culbertson followed hard on the heels of the 1886-87 watershed years for the early cattle industry.

As a result, the first settlers in the area raised horses for the US Cavalry’s various Montana and Dakota posts.

When the agricultural boom went bust after World War II and never resumed its former glory, Culbertson saw a gradual decline in businesses and population.

Culbertson also became a surviving center as smaller adjacent communities dried up in the agricultural depression of the 1920s and 1930s.

With better automobiles and better roads, farmers and ranchers could live farther from centers of trade.

According to the United States Census Bureau, the town has a total area of 0.60 square miles (1.55 km2), all land.

[17] Amtrak’s Empire Builder, which operates between Seattle/Portland and Chicago, passes through the town on BNSF tracks, but makes no stop.
