The 1993 New Jersey State Senate elections were held on November 2.
The election took place alongside Christine Todd Whitman's election as Governor over incumbent Jim Florio. Republicans defended the large majority they gained in the 1991 landslide elections, though Democrats did win back two of the seats they lost in that election, and picked up a third seat in an upset over incumbent John H. Dorsey.
This election featured in the political rises of future Governors Jim McGreevey, who flipped one of the three Democratic gains by defeating Randy Corman, and Chris Christie, who unsuccessfully challenged Senator Dorsey in the Republican primary, possibly undermining Dorsey's re-election campaign.

Seats where the margin of victory was under 10%:
Dorsey initially faced a primary challenge from Chris Christie, but Christie was disqualified when Dorsey challenged his nominating petition signatures as invalid, leaving Dorsey unopposed in the Republican primary.[1]
