2025 New Jersey General Assembly election

The 2025 New Jersey General Assembly election was held on November 4, 2025. 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. Democrats have held a majority in the chamber since 2002, and further expanded their majority in 2023 by 6 seats. Primary elections took place on June 10, 2025. The in-person early voting period for the general election ran from October 25 to November 2, 2025.

The June primary was the first election to be held since a new ballot law went into effect. The new law was intended to replace the "county line" ballot design, which gave favorable ballot placement to party-endorsed primary candidates and which was declared unconstitutional by a federal court in 2024. While the elimination of the "county line" resulted in a highly competitive Democratic primary in the 32nd district, in other districts, party-endorsed Democratic and Republican candidates still prevailed. In the 9th and 10th districts, the Democratic primary resulted in a split between party-endorsed and insurgent candidates.

The election resulted in a Democratic supermajority, as they won the largest majority since 1973 by flipping both seats in the 21st district, and one apiece in the 2nd, 8th, and 25th.
