The 1991 New Jersey State Senate elections were held on November 5. The election took place mid-way through the term of Governor James Florio. The results were a landslide victory for the Republican Party amidst a tax revolt by New Jersey voters. Democrats picked up only one seat, that of Senator Lee B. Laskin. Republicans picked up eleven Democrat seats, winning control of the Senate for the first time since 1974. This was the first election after the 1990 census.

Two years later, Governor Florio narrowly lost re-election to Christine Todd Whitman. As of 2024, this remains the largest total number of seats held by the Republican Party and the largest number of seats gained by the Republican Party in a single election since the current districting scheme was introduced in 1973. This remains the last time the Republicans or any party held a veto-proof majority in the chamber.
