2019 New Jersey elections

A general election was held in the U.S. state of New Jersey on November 5, 2019. Primary elections were held on June 4. The only state positions that were up in this election cycle were all 80 seats in the New Jersey General Assembly and one Senate special election in the 1st Legislative District. In addition to the State Legislative elections, numerous county offices and freeholders in addition to municipal offices were up for election. There was one statewide question on the ballot in 2019, and some counties and municipalities may have had a local question asked. Non-partisan local elections, some school board elections, and some fire district elections also happened in 2019.

State Senate special elections
One special election was held in the 1st Legislative District to complete the unexpired term of Jeff Van Drew. Van Drew resigned on January 2, 2019, following his election to Congress. On January 7, Democratic committee members in Atlantic, Cape May, and Cumberland counties selected Assemblyman Bob Andrzejczak as the appointed replacement, and he was sworn in on January 15. Andrzejczak was later defeated in the special election in November by Republican Mike Testa.

An additional vacancy in the State Senate was created by the September 2019 death of Anthony Bucco. The deadline for a 2019 special election having passed, a special election will be held in 2020 pending which his son Tony Bucco was appointed by a party convention to hold the seat on an interim basis.

General Assembly
 The 2019 Elections for New Jersey's General Assembly  was held on November 5, 2019. All 80 seats in the Assembly were up for election. The candidates that won in November will be part of the 219th New Jersey Legislature.

All 80 seats of the New Jersey General Assembly were up for election. Democrats held a 54–26 supermajority 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.

Going into the 2019 election, every legislative district was represented by two Assembly members of the same party. This was maintained afterward, as Republicans flipped both seats in the 1st district.

Ballot measures
One statewide question was on the ballot which was approved by voters:
 * Public Question Number 1, Extends veterans' property tax deduction to continuing care retirement communities providing housing to veterans.
