The 83rd Oregon Legislative Assembly is the current session of the Oregon Legislature. It began on January 21, 2025.[2][3][4] Democrats netted one seat in both the House and the Senate to win a three-fifths supermajority in both chambers, which is required to pass new taxes or update existing taxes, holding 36 seats in the House and 18 in the Senate after the 2024 election.[5] However, they fell short of the two-thirds majority required to unilaterally meet quorum in both houses, needing 2 more seats in the Senate and 4 more seats in the House.
This majority was later expanded by one to 37-23 in the House prior to the 2026 short session, as Cyrus Javadi of Tillamook switched parties from Republican to Democrat.[6]
Senate
Current makeup of the Oregon Senate in the 83rd Oregon Legislative Assembly.
There are eight freshman senators in this legislative session, six of them Republicans due in part to the 2023 Senate walkout and the passage of Measure 113 denying legislators with 10 or more unexcused absences from running for re-election.[8]
Retirements, vacant seats, and election losses led to 11 freshman members of the House during this legislative session.[11] Only one of these new members was due to an incumbent being defeated by a challenger from an opposing party, with Democrats gaining one seat from the previous session due to Lesly Muñoz defeating incumbent Republican Tracy Cramer by just 161 votes.[12] However, two Republican legislators (Charlie Conrad and James Hieb) were defeated in their party's primary elections. They were replaced by Darin Harbick and Christine Drazan, respectively.
On September 5, 2025, Cyrus Javadi, originally elected as a Republican, changed his party registration to the Democratic Party, giving the Democrats a 37-23 majority for the short session in 2026.[13]
