2021 New Jersey General Assembly election

The 2021 New Jersey General Assembly election was held on November 2, 2021. New Jersey voters elected two assembly members in all of the state's legislative districts for a two-year term to the New Jersey General Assembly.

All 80 seats of the New Jersey General Assembly were up for election. Democrats held a 52-28 majority in the lower house prior to the election. The members of the New Jersey Legislature are chosen from 40 electoral districts. Each district elects one state senator and two state assembly members. New Jersey uses coterminous legislative districts for both its State Senate and General Assembly.

Ultimately, Republicans gained six seats in the chamber, reducing Democrats' majority to 46–34. They flipped both seats in the 2nd, 3rd, and 11th districts.
