Oklahoma's sixth congressional district is a former Congressional district in western Oklahoma. Oklahoma gained 3 seats from the 1910 census, but elected the extra seats at-large in 1912. The sixth district was thus actually created and used for the 1914 House election. Oklahoma has gradually lost seats since the 1910 census, and lost its 6th seat in the 2000 census. This resulted in the district being disbanded in 2003; most of its territory is now the 3rd District.
