The 2024 United States presidential election in New Jersey took place on Tuesday, November 5, 2024, as part of the 2024 United States elections in which all 50 states plus the District of Columbia participated. New Jersey voters chose electors to represent them in the Electoral College via a popular vote. The state of New Jersey has 14 electoral votes in the Electoral College, following reapportionment due to the 2020 United States census in which the state neither gained nor lost a seat.
New Jersey has backed the Democratic candidate in every presidential election since 1992. Kamala Harris was widely expected to win the state, which she did by a 5.91% margin, marking the first single-digit margin of victory for a Democrat in the state since 2004. This is the closest a Republican has come to winning in New Jersey since 1992.
While Trump gained nearly 100,000 votes from 2020, Harris received nearly 400,000 fewer votes than Biden. Trump received the most votes in New Jersey of any Republican presidential nominee, surpassing Ronald Reagan's 1984 raw vote total.
New Jersey had the second-largest swing to the right from the 2020 election after neighboring New York. New Jersey joined most other blue and blue-leaning states such as New York and California in seeing significant rightward shifts in 2024. New Jersey was also the only state that voted for Hillary Clinton in 2016 and Joe Biden in 2020 by double digits that Harris won by a single digit margin in 2024.

Analysis
Trump retook Gloucester County and Morris County, both of which he won in 2016 but lost to Biden in 2020. Additionally, Trump is the first Republican to win Passaic County since 1992, as well as Atlantic County and Cumberland County since 1988, while also being the first Republican presidential candidate to win a majority of the state's counties since 1992.
The largest swings were in North Jersey, although Trump also flipped counties in South Jersey. This is likely related to North Jersey being part of the New York metropolitan area, which swung heavily to the right in this election.
Trump's success in New Jersey was partially attributed to his success among Hispanic and Latino Americans and Italian Americans, who shifted hard to the right nationally. This was seen in most of New Jersey's majority-Hispanic towns, which collectively shifted 25% to the right, a much higher rate than the state of New Jersey as a whole. In some majority-Hispanic cities, the Democratic Party's margin collapsed by as much as over 30% (Perth Amboy's margin shrunk by 33%), an underperformance that helped Trump flip Hispanic-plurality Passaic County. This was attributed by Republican strategists on the ground to a perceived overly strong focus on identity politics and immigration instead of household issues. Trump's success did not, however, translate down-ballot, as most Democratic legislators put up double-digit overperformances compared to Harris, a phenomenon that appeared to be partially due to Trump-supporting Hispanics voting for Trump and leaving the rest of the ballot empty. With this election, and Republican Jack Ciattarelli's strong performance in the 2021 gubernatorial election, some analysts believed New Jersey has transitioned from a reliable blue state into a potential swing state, although Democrats put up a double digit win in the 2025 New Jersey gubernatorial election.
