Preston is a small unincorporated community located in Okmulgee County, Oklahoma. The post office was established December 13, 1909. It was named for an Okmulgee oilman, Harry Preston.Unrecognizable from the past, Preston was once a highly prosperous community, thriving mainly from the oil boom as did many of the surrounding communities. Later on, as the oil industry quieted in Preston, it served as a station for restocking trains and running cattle trails, loading water from Frisco lake.
