Disqualification

Due to the 2023 Oregon Senate walkout, these Republican Senators are barred from running for state legislative office in this election:

1. Sen. Cedric Ross Hayden from District 6
2. Sen. Kim Thatcher from District 11
3. Sen. Suzanne Weber from District 16

Electoral system

The 15 members of the Senate up for election were elected from single-member districts via first-past-the-post voting for four-year terms.

Contested nominations of recognized major parties (Democratic and Republican) for each district are determined by a primary election on May 19, 2026.

Minor party candidates are nominated by petition. Write-in candidates must file a request with the Secretary of State's office for votes for them to be counted. Candidates for the state Senate in 2026 are required to file to run from September 11, 2025, to March 10, 2026. ^[4]
