The Mob Museum is a 501(c)3 nonprofit organization with a mission to advance the public understanding of organized crime’s history and impact on American society. The Mob Museum offers a bold and authentic view of organized crime from vintage Las Vegas to the back alleys of American cities and—increasingly—across the borders and networks of the entire world. Explore the real stories and actual events of Mob history through interactive exhibits and one-of-a-kind Mob and law enforcement artifacts found inside our restored 1933 former courthouse and post office building located just minutes from Fremont Street.
