Bầu cử thống đốc New Jersey năm 2017

The 2017 New Jersey gubernatorial election was held on November 7, 2017, to elect the governor of New Jersey. Incumbent Republican governor Chris Christie was term-limited and ineligible to seek re-election to a third consecutive term. Former U.S. Ambassador to Germany, Phil Murphy and former Speaker of the Assembly Sheila Oliver won the gubernatorial election in a landslide, defeating incumbent lieutenant governor Kim Guadagno and the incumbent Mayor of Woodcliff Lake Carlos Rendo by a wide margin of 14.14%. This election was one of the first major races that took place during Donald Trump's first presidency.

Primary elections took place on June 6, 2017. Kim Guadagno, the incumbent lieutenant governor of New Jersey, won the Republican primary for governor and chose Woodcliff Lake Mayor Carlos Rendo as her running mate. Phil Murphy, a banker and former U.S. Ambassador to Germany, won the Democratic primary, and chose former State Assembly Speaker Sheila Oliver as his running mate. Seth Kaper-Dale ran as the Green Party candidate with Lisa Durden, while Pete Rohrman ran as the Libertarian Party candidate with Karrese Laguerre. Matt Riccardi ran as the Constitution Party candidate. There were two other independent candidates on the ballot.

Murphy led throughout the general election, with many analysts expecting a Democratic pickup. When polls closed on Election Day, Murphy was immediately declared the winner, based on exit polling alone. Murphy received 56.0% of the vote to Guadagno's 41.9%. Murphy slightly outperformed Hillary Clinton's 2016 presidential run in the state, and won one county (Gloucester) that Clinton lost in 2016, while Guadagno didn't win any county that Clinton won in 2016. With the election of Sheila Oliver as lieutenant governor, she became the first woman of color elected to statewide office in New Jersey. 38.5% of registered voters cast ballots, marking the lowest turnout on record for any gubernatorial election in New Jersey. Guadagno later left the Republican Party in July 2021.

2017 was the first New Jersey gubernatorial election since 1989 in which the Democratic candidate won Somerset County, as well as the first since 2005 in which the Democratic candidate won Burlington County, Middlesex County, Atlantic County, or Gloucester County. Murphy became the first New Jersey governor since Brendan Byrne in 1973 to win without any prior elected experience, and the first since Charles Edison in 1940 to win without having held any prior public office in the state. This is the first gubernatorial election since 1937 in which the Democratic nominee won without winning Salem County, and the first since 1981 that it voted for the losing candidate.
