Luigi Nicholas Mangione (/ˌmæniˈni/ MAN-jee-OH-nee; born May 6, 1998) is an American man accused of killing Brian Thompson, the CEO of UnitedHealthcare.

Thompson was shot and killed in New York City on December 4, 2024. Following a nationwide manhunt, Mangione was arrested in Altoona, Pennsylvania, five days after the shooting. He was indicted on eleven state charges and four federal charges, including first-degree murder in furtherance of terrorism, criminal possession of a weapon, and stalking. Federal prosecutors initially sought the death penalty in Mangione's federal case. On September 16, 2025, a New York state judge dismissed Mangione's two terror-related murder charges; he still faces a charge of second-degree murder. On January 30, 2026, a federal judge dismissed two federal charges: the firearms charge and the federal murder charge that carried the possibility of the death penalty.

Since his arrest, Luigi Mangione has received significant public attention. According to polls, a large proportion of Americans hold negative views of Mangione, while a minority view him favorably. Portrayals of Mangione as a folk hero have been tied to negative public opinion of the U.S. health insurance industry and claim denial practices.
