This is a chronological listing of the United States senators from New Jersey. Since the enforcement of the Seventeenth Amendment to the United States Constitution, U.S. senators are popularly elected for a six-year term beginning January 3. Elections are held the first Tuesday after November 1. Before 1914, they were chosen by the New Jersey Legislature, and before 1935, their terms began March 4. The state's current senators are Democrats Cory Booker (serving since 2013) and Andy Kim (serving since 2024). Frank Lautenberg was New Jersey's longest-serving senator (1982–2001; 2003–2013).
