The Three Rivers Museum of Muskogee was established in 1989 as the dream of local historian Dorothy Ball, who was the chairman of the Muskogee Historic Preservation Commission. The museum was created to provide a location to collect, preserve, research, interpret and exhibit artifacts that illustrate the history and heritage of the Three Rivers area of Eastern Oklahoma. The Three Rivers area includes: Muskogee, Wagoner, Cherokee, McIntosh, Okmulgee, Haskell, Southern Mayes and Western Sequoyah Counties.
