1997 New Jersey Senate election

The 1993 New Jersey State Senate elections were held on November 4.

The election took place alongside Christine Todd Whitman's re-election as Governor over Senator Jim McGreevey. Republicans defended the large majority they gained in the 1991 landslide elections.

Four seats changed hands with no impact on the overall balance of power. Republicans Anthony R. Bucco and Diane Allen unseated incumbent Gordon MacInnes and gained the seat of retiring Senator Jack Casey, respectively. Democrats Shirley Turner and Garry Furnari unseated incumbent Republicans Dick LaRossa and John P. Scott, respectively. One Senator, Republican Joseph Bubba, lost a primary. His challenger, Norman M. Robertson, held the seat for the Republicans. This remains the last time that Republicans won a Senate majority.
