county in Oklahoma, United States
Seminole County is a county located in the U.S. state of Oklahoma. As of the 2020 census, the population was 23,556. Its county seat is Wewoka. Most of the county was a reservation for the Seminole Nation of Oklahoma which still retains jurisdiction over some land in the county.

Seminole County is notable for the Greater Seminole Field, one of the most important oil fields ever found, which is still producing. It extends into nearby counties.
