Louis "Little New York" Campagna (March 31, 1900 – May 31, 1955) was an American gangster and mobster and a high-ranking member of the Chicago Outfit for over three decades.

[2] In 1919, New York mobster Al Capone moved to Chicago to help South Side Gang boss John Torrio deal with rival bootleggers.

[3] In the long bloody war with the rival North Side Gang, Campagna proved to be a reliable gunman.

During this violent period, Campagna reportedly slept on a cot outside Capone's suite at Chicago's Lexington Hotel, ready to protect his boss.

Bootlegger Joe Aiello, an ally of the North Side Gang, had unsuccessfully attempted to bribe a hotel chef to poison Capone.

[4] During the early 1940s, Campagna extorted $1 million from the U.S. film industry through the takeover of the International Alliance of Theatrical, Stage Employees & Motion Picture Operators Union in Los Angeles.

On March 18, 1943, Campagna and other Outfit mobsters were indicted in New York on charges of extorting the Hollywood film industry.

In the late 1940s, a group of Campagna associates collected over $190,000 to pay his tax debt to the federal government (reduced from $470,000).

[2] Outfit boss Anthony Accardo had reportedly bribed a district attorney to facilitate Campagna's quick release.

[8] In his later years, Campagna spent time at his two farms in Fowler, Indiana and Berrien Springs, Michigan, as well as his house in Berwyn, Illinois.

[1][2] Since the Roman Catholic Church denied Campagna a Requiem Mass, a memorial service was held at a funeral home in Berwyn, Illinois.

Campagna was buried at Mount Carmel Cemetery, in Hillside, Illinois, in what observers described as the most lavish mob funeral since Capone's death.
