Julia Salazar (born December 30, 1990) is an American politician and activist. She is the New York State Senator for the 18th district, which covers much of northern Brooklyn, centered on Bushwick. She won the seat as a first-time candidate after unseating incumbent Senator Martin Malave Dilan in the Democratic Party primary in 2018. She attracted national media attention for her support for sex workers' rights and other views. A member of the Democratic Socialists of America, she became the first member of the organization to serve in New York's state legislature.

Salazar was born in Miami on December 30, 1990. Her mother is an American citizen by birth, and her father a naturalized American citizen from Colombia. Her parents divorced during her childhood. Salazar was raised in a secular conservative home and at 18 registered as a Republican. In March 2010, she registered with the Independence Party of New York, believing it meant she was an independent voter.

Salazar attended Columbia University, but did not earn a degree. While there, Salazar was pro-life and a member of pro-Israel Christian student groups, but after a trip to Israel with Birthright Israel, her political views began to shift and she became involved in campus Jewish life and tenant organizing. After college, she became a grassroots organizer and campaigned extensively for legislation around police accountability.

While attending college, Salazar worked as a nanny for four years on the Upper West Side and as a housecleaner, and in combination with her study of Middle Eastern history this led her to become more class-conscious. She began as an activist by organizing a tenant group with which she launched a rent strike against poor conditions in her housing block. She then worked at a social justice non-profit, Jews for Racial and Economic Justice (JFREJ) as an organizer.

In April 2018, Salazar announced her candidacy for the 18th district of the New York State Senate in the Democratic primary against incumbent Senator Martin Malave Dilan, who had held his position since 2002.

She ran as a democratic socialist. Her campaign gained significant attention after the primary victory of Alexandria Ocasio-Cortez in New York's 14th congressional district. She was endorsed by Our Revolution, the Democratic Socialists of America, Cynthia Nixon, and Ocasio-Cortez herself. Citizens Union initially endorsed her but later revoked their endorsement, citing discrepancies in information she provided about her academic credentials.

On September 13, 2018 Salazar defeated Dilan for the Democratic Party nomination. She was elected unopposed at the November 6 general election.

Salazar handily won re-election in 2020, with 86.7% of the votes in the Democratic primary, and 97.5% in the general election.
