Jeffrey Edward Epstein (, EP-steen; January 20, 1953 – August 10, 2019) was an American financier and child sex offender. Born and raised in New York City, Epstein began his professional life as a teacher at the Dalton School despite lacking a college degree. After his dismissal from the school in 1976, he entered the banking and finance sector, working at Bear Stearns in various roles before starting his own firm. Epstein cultivated an elite social circle and procured many women and children whom he and his associates sexually abused.

In 2005, police in Palm Beach, Florida, began investigating Epstein after a parent reported that he had sexually abused her 14-year-old daughter. Federal officials identified 36 girls, some as young as 14 years old, whom Epstein had allegedly sexually abused. Epstein pleaded guilty and was convicted in 2008 by a Florida state court of procuring a child for prostitution and of soliciting a prostitute. He was convicted of only these two crimes as part of a controversial plea deal, and served almost 13 months in custody but with extensive work release.

Epstein was arrested again on July 6, 2019, on federal charges for the sex trafficking of minors in Florida and New York. He died in his jail cell on August 10, 2019. The medical examiner ruled that his death was a suicide by hanging. Epstein's lawyers have disputed the ruling, and there has been significant public skepticism about the true cause of his death, resulting in numerous conspiracy theories. Since Epstein's death precluded the possibility of pursuing criminal charges against him, a judge dismissed all criminal charges on August 29, 2019. Epstein had a decades-long association with the British socialite Ghislaine Maxwell, who recruited young girls for him, leading to her 2021 conviction on U.S. federal charges of sex trafficking and conspiracy for helping him procure girls, including a 14-year-old, for child sexual abuse and prostitution.
