Boyd is a census-designated place and unincorporated community in Carbon County, Montana, United States. As of the 2010 census it had a population of 35.[2] Boyd was a stop on the Northern Pacific Railway en route to Red Lodge. A post office was first established at Boyd on March 12, 1909 with Roland N. Doughty as the town's first postmaster.[3] Since December 3, 1965, the office has operated as a rural station or a CPO of Roberts with the ZIP code of 59013.
As a station for the Northern Pacific Railway, Boyd prospered. Once travel by automobile became common, the town's economy declined.[4]
Situated on U.S. Route 212, Boyd is about 21 miles from Red Lodge. The turnoff to Cooney Reservoir is in town.
