2021 United States state legislative elections

The 2021 United States state legislative elections were held on November 2, 2021. Three legislative chambers in two states, New Jersey and Virginia, held regularly scheduled elections. These off-year elections coincided with other state and local elections, including gubernatorial elections in both states.

As a result of the elections, New Jersey retained its Democratic trifecta, while a divided government was established in Virginia, as Republicans won back the lower house of the Virginia legislature, which they lost two years earlier.
