Oklahoma's 1st congressional district is in the northeastern corner of the state.

Principal cities in the district (other than Tulsa) include Broken Arrow, Bixby, Jenks, Owasso, Sand Springs, and Wagoner.

The district is currently represented by Republican Kevin Hern who defeated Democratic nominee Tim Gilpin to replace Jim Bridenstine, who resigned to become NASA Administrator in 2018.

Oklahoma's longest serving Senator, Jim Inhofe, represented this district from 1987 to 1994.

His four successors, Steve Largent, John Sullivan, Jim Bridenstine, and Kevin Hern have all been Republicans.
