Oklahoma's 6th congressional district

Oklahoma's 6th congressional district is a former U.S. congressional district in Western Oklahoma. Oklahoma gained three seats in the 1910 census, but elected the extra seats at-large in 1912. The 6th district was thus created and first used for the 1914 House election (as well as the 7th and 8th districts). Oklahoma has gradually lost seats since the 1910 census; it lost its sixth seat in the 2000 census.

In its final configuration, it stretched across the western third of the state, from the Oklahoma Panhandle through Enid, Cheyenne and Altus to downtown Oklahoma City. Since 2003, most of the territory that was in the final configuration of the 6th district has been in the 3rd district.
