Oregon's 1st congressional district

Oregon's 1st congressional district is a congressional district located in the U.S state of Oregon. The district stretches from Portland's western suburbs and exurbs, to parts of the Oregon coast. The district includes the principal cities of Beaverton, Hillsboro, and Tigard, all located in the Portland metropolitan area. Geographically, the district is located in the northwest corner of Oregon. It includes all of Clatsop, Columbia and Tillamook Counties, most of Washington County excluding the extreme southeast, and a portion of southwest Multnomah County in Portland.

The district has been represented by Democrat Suzanne Bonamici since 2012. Bonamici won a special election to replace David Wu, who resigned in the wake of accusations of sexual misconduct.
