"The Untouchables" is an American crime drama that ran from 1959 to 1963 on the ABC Television Network, produced by Desilu Productions. Based on the memoir of the same name by Eliot Ness and Oscar Fraley, it fictionalized Ness' experiences as a Prohibition agent, fighting crime in Chicago in the 1930's with the help of a special team of agents handpicked for their courage, moral character, and incorruptibility, nicknamed the Untouchables. The book was later made into a film in 1987 (also called "The Untouchables") by Brian De Palma, with a script by David Mamet, and a second, less-successful TV series in 1993.

The terse narration by gossip columnist Walter Winchell, in his distinctive New York accent, was a stylistic hallmark of the series, along with its melancholy theme music by Nelson Riddle and its shadowy black-and-white photography, influenced by film noir.

The show drew harsh criticism from some Italian-Americans, including Frank Sinatra, who felt it promoted negative stereotypes of them as mobsters and gangsters. The Capone family unsuccessfully sued CBS, Desilu Productions, and Westinghouse Electric Corporation for their depiction of the Capone family.

"The Untouchables" was an unusually violent program for its time and its excessive violence and surprisingly frank depictions of drug abuse and prostitution were described by the National Association for Better Radio and Television as "not fit for the television screen".
