The 2021 New Jersey State Senate election was held on November 2, 2021. New Jersey voters elected state senators in all of the state's legislative districts for a two-year term to the New Jersey Senate. Republicans flipped the 3rd and 8th districts, and Democrats flipped the 16th. This was the first election since 1991 where Republicans posted a net gain of state Senate seats. Democrats would later be restored to 25 seats following the party switch of Samuel D. Thompson in 2023.
