New Jersey's 3rd congressional district is a suburban district in southern and central New Jersey. Centrally located on the I-95 corridor in the Northeast Megalopolis, at the cross-roads between the greater Philadelphia metropolitan area and the Raritan Valley region within the larger New York metropolitan area, the district includes large swaths of Burlington County, and portions of Mercer and Monmouth Counties. It is currently represented by Democrat Herb Conaway of Delran Township, who was elected to succeed Andy Kim of Moorestown and took office in January 2025, after Kim stepped down to take office in the United States Senate.

Under the 2020 census map, the 3rd district lost all of its municipalities in Ocean County, and gained several towns in Burlington, Mercer, and northern and western Monmouth Counties.
