1997 New Jersey Senate election

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.

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.

This remains the last time that Republicans won a Senate majority.
