Arkoma is a town in LeFlore County, Oklahoma, United States. It is part of the Fort Smith, Arkansas-Oklahoma Metropolitan Statistical Area. The population was 1,989 at the 2010 census, a decline from 2,180 in 2000. The name of the town is a portmanteau of Arkansas and Oklahoma. Throughout its history, Arkoma has served as a "bedroom community" because many residents commuted to work in Fort Smith.

The community of Arkoma was established circa 1911 on land owned by Captain James Reynolds, a Civil War veteran who had married into the Choctaw Nation. He chose to turn his property into a suburb of Fort Smith. He built houses to rent. He persuaded the Fort Smith Light and Traction Company to construct tracks and operate an electric trolley route to his new community. The streetcar line ceased operating in 1917.

Arkoma was incorporated as a town in 1946.

Arkoma is located on the same side of the Arkansas River as Fort Smith, Arkansas, and is bounded by the Poteau River to the west and north, and the Arkansas-Oklahoma state line to the east.
