New Jersey's 2nd legislative district is one of 40 in the state, covering the Atlantic County municipalities of Absecon, Atlantic City, Brigantine, Egg Harbor Township, Galloway Township, Hamilton Township, Linwood, Longport, Margate City, Northfield, Pleasantville, Port Republic, Somers Point and Ventnor City as of the 2021 apportionment.

[5] For the 2024-2025 session, the 2nd legislative district of the New Jersey Legislature is represented in the New Jersey Senate by Vincent J. Polistina (R, Egg Harbor Township) and in the General Assembly by Don Guardian (R, Atlantic City) and Claire Swift (R, Margate City).

During the period of time after the 1964 Supreme Court decision in Reynolds v. Sims and before the establishment of a 40-district legislature in 1973, the 2nd District was based around Atlantic County except for the 1965 Senate elections.

Republican Frank S. Farley won the 1967 Senate election but was defeated by Democrat Joseph McGahn in 1971.

[15] In the 2001 redistricting, Egg Harbor City returned to the 2nd but Somers Point shifted to the 1st District.
