Paul Kelly was an American mobster and former boxer, who founded the Five Points Gang in New York City. He had started some brothels with prize money earned in boxing. Five Points Gang was one of the first dominant street gangs in New York history. Kelly recruited young, poor men from the ethnically diverse immigrant neighborhoods of Lower Manhattan. The Five Points Gang included some who later became prominent criminals in their own right, including Johnny Torrio, Al Capone, Lucky Luciano, Meyer Lansky and Frankie Yale.

The Five Points Gang was a criminal street gang of primarily Irish-American origins, based in the Five Points of Lower Manhattan, New York City, during the late 19th and early 20th century.
