## History

The Fort Smith and Southern Railway built a north–south line through what is now Le Flore County in 1886; the line was sold the next year to the St. Louis and San Francisco Railroad ("the Frisco"). In 1903–04 the Midland Valley Railroad laid an east-west line. The settlement originally known as Maney Junction developed at the crossing of these railroads.
A post office was established as Rock Island, Indian Territory on February 1, 1905. It was presumably named for Rock Island, Illinois. At the time of its founding, the community was located in Skullyville County, part of the Moshulatubbee District of the Choctaw Nation.
Rock Island started the process of incorporation in 1989, but the County Commissioners did not approve the incorporation until 2004.
