Seminole County is a county located in the U.S. state of Oklahoma. As of the 2020 census, the population was 23,556.^[1] Its county seat is Wewoka.^[2] Most of the county was a reservation for the Seminole Nation of Oklahoma which still retains jurisdiction over some land in the county. A small portion of land at the eastern end of the county belonged to the Muscogee (Creek) Nation.

Seminole County is notable for the Greater Seminole Field, one of the most important oil fields ever found, which is still producing.^[3] It extends into nearby counties. In the early years of the oil boom, workers and adventurers flooded into the county, rapidly tripling the population. As oil production later declined, jobs and residents left.
