2010 Oregon legislative election

The 2010 elections for the Oregon Legislative Assembly determined the composition of both houses for the 76th Oregon Legislative Assembly. The Republican and Democratic primary elections were on May 18, 2010, and the general election was held on November 2, 2010. Sixteen of the Oregon State Senate's thirty seats were up for election, as were all 60 seats of the Oregon House of Representatives.

In the previous session, the Democrats held supermajorities in both chambers: 18–12 in the Senate and 36–24 in the House. Following the election, Republicans reduced the Democratic majority to 16–14 in the Senate and gained enough seats in the House to make the chamber evenly divided between the parties, 30–30.^[1]
