Oregon's 4th congressional district represents the southern half of Oregon's coastal counties, including
Coos,
Curry,
Lincoln,
Lane, and
Benton counties, alongside the northwestern half of
Douglas County. It is centered around the state's two college towns,
Eugene and
Corvallis, homes to the
University of Oregon and
Oregon State University, respectively. Politically, the district leans slightly Democratic, due to the presence of Lane County, home to almost half of the district's population, and similarly blue Benton and Lincoln Counties. Contrariwise, Douglas County is heavily Republican, as are to a lesser extent Coos and Curry. The district has been represented by
DemocratVal Hoyle since 2023.
The district gained most of Josephine County from the
2nd district in the 2002 redistricting, but also lost most of the
Grants Pass area to the second district.[3][4]
