2021 New Jersey gubernatorial election

The 2021 New Jersey gubernatorial election was held on November 2, 2021, to elect the governor of New Jersey. Incumbent Governor Phil Murphy was first elected in 2017 with 56% of the vote and won re-election to a second term. Murphy and his running mate, Lt. Gov. Sheila Oliver, defeated the Republican ticket of Jack Ciattarelli and Diane Allen, 51.2% to 48%.

Murphy formally announced his intention to run for a second term on October 1, 2020. Primaries were held on June 8, 2021. Murphy, who won the Democratic nomination unopposed after his two primary challengers were disqualified, faced Ciattarelli, Green nominee Madelyn Hoffman, Libertarian nominee Gregg Mele, and Socialist Workers Party nominee Joanne Kuniansky in the general election. The race was considered by many media outlets to be a "safe" or "likely" Democratic hold, as Murphy had led a majority of pre-election polls by double digits. However, Murphy defeated Ciattarelli by a much smaller margin than expected.

Murphy is the first Democratic governor of New Jersey to win re-election since Brendan Byrne in 1977, as well as the first candidate of the same party as the incumbent U.S. president to win since Thomas Kean in 1985. This is also the first New Jersey gubernatorial election since 2009 where both the Democratic and Republican nominees received more than one million votes each. It also was the first New Jersey gubernatorial election where the Green Party candidate placed third. Murphy also became the first Democrat to win a New Jersey gubernatorial election without carrying Gloucester and Cumberland Counties since Robert B. Meyner in 1953, and the first Democrat to win a gubernatorial election without carrying Atlantic County since Richard J. Hughes in 1961.
