1982 United States Senate election in New Jersey

• Millicent Fenwick, U.S. Representative from Bernardsville
• Jeff Bell, political consultant and nominee for the U.S. Senate in 1978

• Angelo Bianchi, former State Banking Commissioner[2]
• Donald Cresitello, former Morristown mayor
• Frank Forst, former Jamesburg mayor[2]
• Frank Lautenberg, financial executive
• Joseph A. LeFante, former U.S. Representative
• Andrew Maguire, former U.S. Representative
• Richard D. McAleer, car leasing agent[2]
• Howard Rosen, attorney[2]
• Barbara Boggs Sigmund, Mercer County Freeholder

Cresitello dropped out of the race on May 27 but remained on the June 8 primary ballot.[3]

The seat had been occupied by Democrat Harrison A. Williams, who resigned on March 11, 1982, after being implicated in the Abscam scandal. After Williams' resignation, Republican Governor Thomas Kean appointed Republican Nicholas F. Brady to the seat. Brady served in the Senate through the primary and general elections but did not run for the seat himself.

In the general election, Lautenberg faced popular Republican congresswoman Millicent Fenwick. She ran on a very progressive platform and polls in the Summer of 1982 put her ahead by 18 points. Even Lautenberg quipped that she was "the most popular candidate in the country."[4] Lautenberg spent more of his own money, eventually out-spending Fenwick two-to-one. He emphasised President Reagan's unpopularity, reminded the voters that she would be a vote for a Republican majority in the Senate and called Fenwick, who was 72, "eccentric" and "erratic" but denied that he was referring to her age.[4][5] He did however point out that she would be almost 80 at the end of her first term and was therefore unlikely to gain much seniority in the Senate.[4] Coincidentally, the age issue would be used against Lautenberg in his own re-election bid in 2008.

Lautenberg won by 51% to 48%, in what was considered a major upset.[4] Brady, who had just a few days left in his appointed term, resigned on December 27, 1982, allowing Lautenberg to take office several days before the traditional swearing-in of senators, which gave him an edge in seniority over the other freshman senators.
