The legislative district overlaps with New Jersey's 1st and 2nd congressional districts.

The 1964 Supreme Court decision in Reynolds v. Sims required legislative districts' populations be equal as possible. As an interim measure, the 3rd District in the 1965 State Senate election encompassed all of Camden County and elected two members to the Senate. In this case, Republican Frederick Scholz and Democrat A. Donald Bigley were sent to Trenton for a two-year term beginning in 1966.

For the next three elections, the 3rd District became made up of all of Camden, Gloucester, and Salem counties and was further divided into four Assembly districts (Districts 3A, 3B, 3C, and 3D). In the 1967 and 1971 Senate elections, a total of four Senators were elected from the district but candidates were nominated by Assembly district and were elected by only the residents of the respective district. Each Assembly district elected two members in each election.

The members elected to the Senate from each district are as follows:
