The '''2018 elections''' for the [[Oregon Legislative Assembly]] determined the composition of both houses for the [[80th Oregon Legislative Assembly]]. The [[Republican Party (United States)|Republican]] and [[Democratic Party (United States)|Democratic]] parties held primary elections on May 15, 2018, with general elections on November 6, 2018.

As a result of the elections, the [[Oregon Democratic Party|Democratic Party]] expanded its advantage in both houses of the state legislature. The party gained one seat in the [[Oregon State Senate]] and three seats in the [[Oregon House of Representatives]], bringing its advantage over the [[Oregon Republican Party|Republican Party]] to 18–12 and 38–22, respectively. These gains gave the Democratic Party a 3/5 (or 60%) [[supermajority]] in both chambers for the 80th Oregon Legislative Assembly.<ref>{{cite web|url=https://www.statesmanjournal.com/story/news/politics/2018/11/06/oregon-democrats-secure-supermajority-oregon-legislature-senate-house-election-results/1916885002/|title=Oregon Democrats secure supermajorities in both chambers of Oregon Legislature|date=November 6, 2018|first=Connor|last=Radnovich|work=[[Statesman Journal]]|access-date=June 12, 2019}}</ref> {{Toclimit|limit=3}} {{clear}} ==Oregon Senate== {{Infobox election | election_name = 2018 Oregon State Senate elections | country = Oregon | type = legislative | ongoing = no | previous_election = 2016 Oregon legislative election#Oregon Senate | previous_year = 2016 | election_date = {{Start date|2018|11|06}} | next_election = 2020 Oregon State Senate election | next_year = 2020 | seats_for_election = 17 of 30 seats in the [[Oregon State Senate]] | majority_seats = 16 | image1 = Peter Courtney Senate (cropped).jpg | leader1 = [[Peter Courtney]] | party1 = Democratic Party (US) | leaders_seat1 = [[Oregon's 11th Senate district|11th-Keizer]] | seats_before1 = '''17''' | seats_after1 = '''18''' | seat_change1 = {{increase}}1 | popular_vote1 = '''564,247''' | percentage1 = '''59.23%''' | swing1 = {{increase}}8.28% | title = | before_election = | before_party = Democratic Party (US) | posttitle = | after_election = | after_party = Democratic Party (US) | image2 = Herman Baertschiger.jpg | leader2 = [[Herman Baertschiger Jr.]] | party2 = Republican Party (US) | leaders_seat2 = [[Oregon's 2nd Senate district|2nd-Grants Pass]] | seats_before2 = 13 | seats_after2 = 12 | seat_change2 = {{decrease}}1 | popular_vote2 = 367,063 | percentage2 = 38.53% | swing2 = {{decrease}}5.74% | map_image = Oregon State Senate 2018 Election Results.svg | map_size = 300px | map_caption = '''Results of the elections:'''<br />{{legend0|#0671B0|Democratic gain}}<br />{{legend0|#92C5DE|Democratic hold}} {{legend0|#F48882|Republican hold}}<br />{{legend0|#D3D3D3|No election}} }} The 30 members of the [[Oregon State Senate]] are elected to four-year terms, and only half of those seats (15) are up for election every two years. In addition to these 15 regular elections, there were two special elections to determine who would complete the four-year terms of senators who were replaced during the first half of their term. These 17 seats up for election were represented by 10 Democrats and seven Republicans. The Democrats decreased their advantage over Republicans from 18–12 to 17–13 in the [[2016 Oregon legislative election|2016 election]].
