New Jersey's 5th congressional district is represented by Democrat Josh Gottheimer, who has served in Congress since 2017.

Partly due to a strong performance in Bergen County, Josh Gottheimer unseated 14-year Republican incumbent Scott Garrett in 2016.

This made Garrett the only one of the state's 12 incumbents to lose reelection that year and marked the first time a Democrat won this seat since 1930.

After redistricting in late 2021, which was based on the 2020 census, the 5th lost all of its towns in Warren County.

[4] For the 118th and successive Congresses (based on redistricting following the 2020 United States census), the district contains all or portions of three counties and 65 municipalities.
