The 1965 New Jersey State Senate elections were held on November 2.

The elections were the first held after the Supreme Court's Reynolds v. Sims decision, which held that New Jersey's single-seat county apportionment was unconstitutional. The ruling forced New Jersey to grant multiple seats to its largest counties (and eventually, switch to single-member districts that did not follow county lines).

The election also coincided with a landslide re-election victory for Democratic Governor Richard J. Hughes.

The result was a majority for the Democratic Party, the first since 1915.
