The 2020 United States Senate election in New Jersey was held on November 3, 2020, to elect a member of the United States Senate to represent the State of New Jersey. It was held concurrently with the 2020 United States presidential election, as well as various other elections. The primary elections were moved from June 2, 2020, to July 7, 2020, due to COVID-19 pandemic concerns. Incumbent Senator Cory Booker was first elected in a 2013 special election to complete the term of fellow Democrat Frank Lautenberg, who died in office.
Booker won a second full term against Republican Rik Mehta, narrowly winning Morris County, which no Democratic Senate candidate had carried since 1984 when Senator Bill Bradley swept every county. He also flipped Somerset County, which last voted for a Democrat for this seat in 1984. Booker also received the most votes (2,541,239) in a statewide non-presidential election in New Jersey history.
