Nicholas Joseph LaLota (/ləˈloʊtə/ lə-LOH-tə; born June 23, 1978) is an American politician and veteran serving since 2023 as the U.S. representative for New York's 1st congressional district. He is a member of the Republican Party.

LaLota was born on June 23, 1978, and is from Bay Shore, New York. He graduated from St. Anthony's High School and, in 2000, from the United States Naval Academy. He served in the U.S. Navy for eight years, serving three overseas deployments. He earned a Master of Business Administration and a Juris Doctor from Hofstra University. LaLota served as chief of staff to Suffolk County presiding officer Kevin McCaffrey. He also served on the Suffolk Board of Elections as well as a trustee for the village of Amityville, New York.

LaLota ran for the United States House of Representatives in the first congressional district of New York to succeed Lee Zeldin, who ran for governor of New York. He won the general election on November 8 by defeating the Democratic nominee Bridget Fleming.

On December 27, 2022, LaLota became one of the first Republicans to call for a full House Ethics Committee investigation into the false claims made by his fellow Long Island Republican, representative-elect George Santos. "New Yorkers deserve the truth and House Republicans deserve an opportunity to govern without this distraction", LaLota said. On March 7, 2024, during President Joe Biden's State of the Union address, Santos posted on social media that he planned to run against LaLota in the 2024 Republican primary.

LaLota sought reelection in 2024. He defeated Democratic nominee John Avlon.

LaLota was sworn in on January 7, 2023.

LaLota was one of six Republicans to sign a bipartisan letter spearheaded by centrist House Representatives in which they pledged to respect the results of the 2024 presidential election.
