The 2020 United States state legislative elections were held on November 3, 2020, for 86 state legislative chambers in 44 states. Across the fifty states, approximately 65 percent of all upper house seats and 85 percent of all lower house seats were up for election. Nine legislative chambers in the five permanently-inhabited U.S. territories and the federal district of Washington, D.C. also held elections. The elections took place concurrently with several other federal, state, and local elections, including the presidential election, U.S. Senate elections, U.S. House elections, and gubernatorial elections.

Prior to the elections, Democrats held 15 trifectas (control of the governor's office and legislative chambers), Republicans held 21 trifectas, and 14 states have a divided government. Nationwide, Republicans controlled approximately 60 percent of the legislative chambers and 52 percent of the legislative seats. ^[1] These elections had a major impact on the 2020 redistricting cycle, as many states held their final legislative elections prior to the decennial drawing of new congressional and state legislative districts.

Due to the impact the redistricting cycle will have on partisan control of Congress and state legislatures, the Democrats, who had not been in control of a majority of state legislatures across the U.S. since 2010, had hoped to retake control of key chambers in advance. However, despite fundraising efforts and projections of several Republican-held chambers in competitive states flipping, the Democrats failed to flip any state chambers, which they attributed to gerrymandering in the wake of the 2010 elections, as well as state laws restricting voting, President Donald Trump being on the ballot, and the Democrats' campaigning methods. In fact, Republicans flipped both chambers in the New Hampshire legislature. ^{[2] [3] [4] [5]}

Following the election, Republicans controlled redistricting in 20 state governments, totaling 188 House districts, whereas Democrats had control in states with a total of 73 districts. ^[6] Overall, these elections saw the fewest partisan changes in state legislatures since 1944. ^[7]

Summary table

Regularly scheduled elections were held in 86 of the 99 state legislative chambers in the United States. Nationwide, regularly scheduled elections were held for 5,876 of the 7,383 legislative seats. Many 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. ^[8] The chambers 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 midterm election years.

Note that this table only covers regularly scheduled elections; additional special elections took place concurrently with these regularly scheduled elections.

Electoral predictions

Louis Jacobson of The Cook Political Report predicted that Republican-held chambers that could potentially flip to Democratic control included both chambers in Arizona, the Florida Senate, both chambers in Georgia, the Iowa House, the Michigan House, the Minnesota Senate, both chambers in North Carolina, both chambers in Pennsylvania, and the Texas House. He predicted that Republicans could potentially gain control of the Maine Senate, the Minnesota House, and both chambers in New Hampshire, all of which were controlled by the Democratic Party. Additionally, Jacobson predicted that Republicans could win control of the Alaska House, which was currently controlled by a coalition of Democrats and Republicans. ^[9]

Writing for Sabato's Crystal Ball, Chaz Nuttycombe highlighted the Alaska House and the New Hampshire Senate as the top pick-up opportunities for Republicans, and lists the Arizona House, the Arizona Senate, the Iowa House, the Michigan House, the Minnesota Senate, the North Carolina House, the North Carolina Senate, the Pennsylvania House, and the Texas House as the top pick-up opportunities for Democrats. ^[10]

Most election predictors use:

• "Tossup": No advantage
• "Tilt": Advantage that is not quite as strong as "lean"
• "Lean": Slight advantage
• "Likely": Significant, but surmountable, advantage
• "Safe" or "Solid": Near-certain chance of victory
