Edward J. McGrath (born January 31, 1906 – c. 1994)[1] was an Irish-American crime boss from New York City, who controlled the Hell's Kitchen Irish Mob and the lucrative waterfront throughout the 1940s.

Born to Irish immigrant parents, McGrath grew up in the Gashouse District on the Lower East Side of Manhattan.

McGrath served as an altar boy and sang in the choir at St. Stephen's Roman Catholic Church on East 29th Street.

Eddie McGrath was forced to abscond from New York after Dunn and Sheridan were executed for the murder of a hiring stevedore named Andy Hintz in 1949, and the investigation of waterfront criminal activity subsequently began to escalate.

He left New York in the early 1950s and was living in Miami in 1970, when mobster Hughie Mulligan was reported to be McGrath's "on-premises manager.
