# 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.

## Summary table

Regularly scheduled elections were held in 3 of the 99 state legislative chambers in the United States. Nationwide, regularly scheduled elections were held for 220 of the 7,383 legislative seats. This table only covers regularly scheduled elections; additional special elections took place concurrently with these regularly scheduled elections.
