Stephen Joseph Flemmi (born June 9, 1934) is an American former mobster and convicted murderer and was a close associate of Winter Hill Gang boss Whitey Bulger. Beginning in 1975, Flemmi was a top echelon informant for the Federal Bureau of Investigation (FBI).

Despite delivering a great deal of intelligence about the inner workings of the Patriarca crime family, Flemmi's own criminal activities proved a public relations nightmare for the FBI. He was ultimately brought up on charges under the Racketeer Influenced and Corrupt Organizations Act, and pleaded guilty in return for a sentence of life in prison.
