A Republican Party primary takes place on May 19, 2026, in Oregon to determine which Republican candidate will run in the state's general election on November 3, 2026.

Candidate filing deadline	Primary election	General election
March 3, 2026 (incumbent) March 10, 2026 (non-incumbent)	May 19, 2026	November 3, 2026

Heading into the election, the incumbent is Jeff Merkley (Democrat), who was first elected in 2008.

A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Oregon law allows parties to decide whether unaffiliated voters can vote in their primaries. As of December 2025, both major parties utilized a closed primary process where only registered party members may participate.

For information about which offices are nominated via primary election, see this article.
