Big Arm is a census-designated place (CDP) in Lake County, Montana, United States. The population was 177 at the 2010 census,[2] up from 131 in 2000.

The town is situated on the south side of Big Arm, a large bay on Flathead Lake, hence its name. The name was used by the Kootenai people, who lived there prior to the town being established.[3] The post office opened in 1911, with Marion F. Lamb as postmaster.[4]

Big Arm State Park is located just north of the town.
