The Capo di tutti i capi or capo dei capi (boss of all bosses) is the leader of the Mafia in a particular area, ruling over that country or territory's Commission. It is a phrase used mainly by the media, public and the law enforcement community to indicate a supremely powerful crime boss in the Sicilian or American Mafia who holds great influence over the whole organization. However, it has seldom been given to specific bosses because it could create tension between different families within the Mafia. Typically the title is awarded de facto to the boss of the most powerful crime family. However, for most of these individuals a more realistic description would be "first among equals".
