County Seat: Beaver, OK 73932
The land where Beaver County is located has been under several jurisdictions. At one time, it was part of Texas before Texas became a state of the United States. There was a period of time that it was not part of the Oklahoma Territory but not a separate organized territory. After becoming part of the Oklahoma Territory in 1890, Beaver County (first called Seventh County) covered the entire Oklahoma Panhandle.
