Kingfisher county, created in 1890 following the run into "The Unassigned Lands" and the organization of the Oklahoma Territory, is located in central Oklahoma just northwest of Oklahoma City. The town of Kingfisher serves as the county seat.
The only major waterway in the county is the Cimarron River which enters the northwest corner and exits due east of Kingfisher.
The historic Chisholm Trail, used by cattlmen during drives to the stockyards in Kansas prior to the railroads being established, runs parallel to U.S. Highway 81 and has a museum displaying artifacts from the era in the A.J. Seay Governor's Mansion in Kingfisher. Seay was appointed the second governor of the Oklahoma Territory in 1892 and had a mansion built in anticipation of the territorial capital being moved from Guthrie to Kingfisher-an event that never occurred.
The county population on July 1, 1999, was 13,496, an increase of 284 over the 1990 census.
