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, New Mexico and South Carolina held elections for their lower, but not upper houses.

Republicans scored record gains, gaining at least 680 total seats and taking control of 21 legislative chambers through election, while the Democrats lost 22 chambers.[1][2] Democrats additionally lost 3 chambers due to special elections and party switching. 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.

Due to the 2010 United States Census being held the same year, these elections also held consequences for the following redistricting cycle, in which state legislative majorities redrew maps to protect and extend themselves and the careers of U.S. House members from the same party.
