Douglas County lies within Oregon's 4th congressional district, which also includes the more liberal Eugene metropolitan area and has thus been represented by Democrat Peter A. DeFazio since 1987. Within the Oregon House of Representatives, Douglas County is split between four districts. The coastal part lies within the 9th District represented by Democrat Caddy McKeown, whilst a belt from Roseburg south lies in the 2nd District, which extends into Jackson and Josephine Counties and is represented by Republican Dallas Heard. The far southwest adjacent to Curry County lies in the 1st District represented by Republican David Brock Smith, and the bulk of the county, centered on the northeastern half, lies in the 7th District represented by Republican Cedric Ross Hayden.
