Chouteau County was once the largest county in the Montana Territory and the second largest in the United States, with an area of 15,439 square miles (39,990 km2) in the early 20th century. However, some parts of the county were over 250 miles (400 km) from Fort Benton, and in 1909 an agreement was reached to subdivide the county.

Chouteau County lost half of its population from 1910 to 1930.

The land is mostly prairie. The Bear Paw Mountains rise in the eastern section and the Little Rockies and the Highwood ranges are in the southern portion. Major rivers include the Teton River, Marias River, Missouri River and the Arrow River.
