The Mullen Gang was an Irish-American street gang based in South Boston, Massachusetts, active from the 1950s until 1972. It engaged in racketeering, armed robbery, auto theft, burglary, extortion, loansharking, illegal gambling, and murder. The gang derived its name from a commemorative plaque to war hero John Joseph Mullen. After a decade-long gang war with the Killeen Gang, both groups were consolidated under the Winter Hill Gang in 1972.
