2010 United States state legislative elections
The 2010 United States state legislative elections were held on November 2, 2010, halfway through President Barack Obama's first term in office. Elections were held for 88 legislative chambers, with all states but Louisiana, Mississippi, New Jersey, and Virginia holding elections in at least one house. Kansas and New Mexico held elections for their lower, but not upper houses. Four territorial chambers in three territories and the District of Columbia were up as well.

Republicans scored record gains, gaining at least 680 total seats and taking control of 20 legislative chambers through election, while the Democrats lost 21 chambers.[1][2] The winners of this election cycle were slated to serve in their respective legislatures for either two or four-year terms, depending on state election rules.
Republicans made substantial gains in state legislatures across the nation. Twenty chambers flipped from Democratic to Republican control, giving Republicans full control of eleven state legislatures and control of one chamber in Colorado, Iowa, and New York.1[3] Additionally, Republicans gained enough seats in the Oregon House of Representatives to produce a 30-30 party split, pushing Democrats into a power-sharing agreement that resulted in the election of two "co-speakers" (one from each party) to lead the chamber.[4] Republicans gained a total of 680 seats in state legislative races, breaking the previous record of 628 flipped seats set by Democrats in the post-Watergate elections of 1974.[5]
Six states saw both chambers switch from Democrat to Republican majorities: Alabama (where the Republicans won a majority for the first time since 1874), Maine (for the first time since 1964), Minnesota (for the first time since 1915 in partisan elections and 1973 in non-partisan elections), New Hampshire, North Carolina (for the first time since 1896), and Wisconsin. In addition, by picking up the lower chambers in Indiana, Ohio, Michigan, Montana[lower-alpha 3] and Pennsylvania, Republicans gained control of both chambers in an additional five states. Further, Republicans picked up one chamber from Democrats in Colorado, Iowa, and New York to split control in those states. They expanded majorities in both chambers in Texas, Florida, and Georgia. The massive Republican victories in legislative races would be widely expected to significantly impact the redrawing of congressional districts for the 2012 election cycle.
Summary table
Regularly-scheduled elections were held in 88 of the 99 state legislative chambers in the United States; nationwide, regularly-scheduled elections were held for 6,064 of the 7,383 legislative seats. Most legislative chambers held elections for all seats, but some legislative chambers that use staggered elections held elections for only a portion of the total seats in the chamber.[6] The chambers that were not up for election either hold regularly-scheduled elections in odd-numbered years, or have four-year terms and hold all regularly-scheduled elections in presidential election years.
Note that this table only covers regularly-scheduled elections; additional special elections took place concurrently with these regularly-scheduled elections.

Notes
- The Alaska Senate was controlled by a coalition of Democrats and Republicans. The minority caucus consists of Republicans who were not part of the majority coalition.
- The Oregon House of Representatives was tied in the 2011-2013 session. This is not included in the total.
- Prior to the 2010 election, the 100 seats in the Montana House of Representatives were evenly split between Democrats and Republicans, but the Democratic Party controlled the chamber by virtue of holding the governor's office.
- The upper houses of Arkansas, Delaware, Florida, Hawaii, Illinois, Minnesota, New Jersey, and Texas use a 2-4-4 term length system.
- These figures represent the seats of Nebraska's unicameral legislature.
- Prior to the 2010 election, the 100 seats in the Montana House of Representatives were evenly split between Democrats and Republicans, but the Democratic Party controlled the chamber by virtue of holding the governor's office.
