The2025 Nassau County Executive election will be held on November 4, 2025, to select the County Executive ofNassau County, New York. Incumbent Republican County ExecutiveBruce Blakeman, first elected in2021, is seeking re-election to a second term on theRepublican andConservative ballot lines against challenger Seth Koslow, a County Legislator running on theDemocratic andModerate ballot lines.^[1]

• Bruce Blakeman, incumbent County Executive^[2][1]

• Seth Koslow, county legislator^[3][1][4]

• Bruce Blakeman, incumbent executive^[1]

• Seth Koslow, county legislator^[1]

Koslow announced that he would challenge Blakeman on January 8, 2025, with endorsements from former County ExecutiveLaura Curran, whom Blakeman defeated in2021, and CongressmanTom Suozzi, who was County Executive from 2002 to 2009.^[5] Though Blakeman was at a financial disadvantage in his 2021 campaign,^[6] he outraised Koslow significantly in the first half of the year, raising $2 million to Koslow's $430,000 through July 15.^[7]

Despite PresidentDonald Trump narrowly winning Nassau County in the2024 presidential election,^[5] Koslow has attacked Blakeman over the effects of Trump's tariffs in the county, which Blakeman has defended,^[8] and over the effects of theBig Beautiful Bill on the county.^[9]
