New Jersey's 4th congressional district is a congressional district that stretches from the New Jersey shore to the central part of the state near the capital of Trenton. It has been represented by Republican Chris Smith since 1981, the second-longest currently serving member of the US House of Representatives. With a Cook PVI rating of R+8, it is by far the most Republican district in New Jersey.

In December 2021, the New Jersey Redistricting Commission adopted a new congressional map that will take effect in January 2023 for the following decade. In this map, the 4th district will lose its two towns in Mercer County, becoming entirely contained to Monmouth County and Ocean County.[4]

The district will become one of the most Republican-leaning districts in the northeastern United States following congressional redistricting in 2023.^{[citation needed]}
