2016 United States state legislative elections

The 2016 United States state legislative elections were held on November 8, 2016, 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.

Democrats won both chambers in the Nevada Legislature and the New Mexico House of Representatives, while Republicans won the Kentucky House of Representatives for the first time since 1922, the Iowa Senate, and the Minnesota Senate. The Alaska House of Representatives flipped from Republican control to a Democrat-led coalition majority, and the Connecticut State Senate went from Democratic control to tied control. Meanwhile, the New York Senate went from Republican to a Republican-led coalition.

The Democrats' loss in Kentucky marked the end of the realignment of the conservative South towards the Republicans, as the House of Representatives was the last chamber they held in the region, and the last chamber they controlled in a deeply Republican state. This also gave Republicans a government trifecta in the state for the first time in its history.

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. 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.

News sources predicted Democrats to make mild gains in state legislative control, owing to the historic lows they hit after the 2014 elections and higher predicted turnout among Democratic voters during the concurrent presidential election.

Ratings are designated as follows:

• "Tossup": Competitive, no advantage

• "Lean": Competitive, slight advantage

• "Likely": Not competitive, but opposition could make significant gains

• "Safe": Not competitive at all
