Edward Joseph O'Hare (he used "Edward" later in life), aka "Easy Eddie" (September 5, 1893 – November 8, 1939), was a lawyer in St. Louis and later in Chicago, where he began working with Al Capone, and later helped federal prosecutors convict Capone of tax evasion. In 1939, a week before Capone was released from Alcatraz, O'Hare was shot to death while driving. He was the father of Medal of Honor recipient Butch O'Hare, for whom O'Hare Airport is named.
