Francis "Two Gun" Crowley (October 31, 1912 – January 21, 1932) was an American murderer and career criminal. His crime spree lasted nearly three months, ending in a two-hour shootout with the New York City Police Department in May 1931. The 19-year-old's stand against the NYPD was witnessed by 15,000 bystanders and received national attention. Crowley would later influence the image of the archetypal Irish gangster.
