Two co-defendants, Saddam Hussein's half-brother Barzan al-Tikriti and former Iraqi chief judge Awad Hamed al-Bandar, were also executed.
"Criminal Saddam was hanged to death," state-run Iraqiya television announced, as patriotic music and images of national monuments were broadcast.
A scrolling headline read: "Saddam's execution marks the end of a dark period of Iraq's history."
The hanging of the shotgun-waving dictator was reportedly video taped but the film will probably never be released to the public.
