Alan Morton Dershowitz ( DURR-shə-wits; born September 1, 1938) is an American lawyer known for his work in U.S. constitutional law and American criminal law. From 1964 to 2013 he taught at Harvard Law School, where he was appointed the Felix Frankfurter Professor of Law in 1993. Dershowitz is a regular media contributor, political commentator, and legal analyst.

Dershowitz is known for taking on high-profile and often unpopular causes and clients. As of 2009, he had won 13 of the 15 murder and attempted murder cases he handled as a criminal appellate lawyer. Dershowitz has represented such celebrity clients as Mike Tyson, Patty Hearst, Leona Helmsley, Julian Assange, and Jim Bakker. Major legal victories have included two successful appeals that overturned convictions, first for Harry Reems in 1976, then in 1984 for Claus von Bülow, who had been convicted of the attempted murder of his wife, Sunny. In 1995, Dershowitz served as the appellate adviser on the O. J. Simpson murder trial, part of the legal "Dream Team", alongside Johnnie Cochran and F. Lee Bailey. He was a member of Harvey Weinstein's defense team in 2018 and of President Donald Trump's defense team in his first impeachment trial in 2020. He was a member of Jeffrey Epstein's defense team and helped to negotiate a 2006 non-prosecution agreement on Epstein's behalf. One of Epstein's underage victims accused Dershowitz of rape in a sworn affidavit and in the Netflix documentary Jeffrey Epstein: Filthy Rich, which resulted in a lawsuit and his own countersuit.Dershowitz is the author of several books about politics and the law, including Reversal of Fortune: Inside the von Bülow Case (1985), the basis of the 1990 film; Chutzpah (1991); Reasonable Doubts: The Criminal Justice System and the O.J. Simpson Case (1996); The Case for Israel (2003); and The Case for Peace (2005).
