Oregon's 4th congressional district

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 Democrat Val Hoyle since 2023.
