Most of Rock Island was built recently: 3% of its homes predate 1940 and the median home dates from 1989. Below: maps from 1887 on and the census since 1990.
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.
