Ummah (أمة) is an Arabic word meaning "community" or "nation".

The leader of the ummah is known as the is theoretically to be the Caliph, "Amir Al-Mu'minin" or "Commander of the Believers", although no widely-accepted figure has held this position since the fall of the Ottoman caliphate after the end of the World War I.
