George "Bugs" Moran (1893-1957) was a Chicago Prohibition-era gangster. Moran led a bloody turf war against Al Capone, his archnemesis, for many years. Several associates of Moran were killed by associates of Capone in the notorious St. Valentine's Day Massacre in 1929.

After Prohibition ended, Moran's criminal career declined, and he died in prison while serving time for bank robbery.
