The 2002 United States Senate election in Oregon was held on November 5, 2002. Incumbent Republican United States Senator Gordon Smith ran for re-election to a second term. Oregon Secretary of State Bill Bradbury emerged as the Democratic nominee, and though a competitive gubernatorial election occurred at the same time, Bradbury's campaign was never able to gain traction and Smith overwhelmingly won re-election (Bradbury only carried Multnomah County). As of 2025, this is the last time the Republicans have won a U.S. Senate election in Oregon.
