The title King of Syria was only briefly used with the only king being Faisal who was proclaimed monarch after the Arab Revolt on March 11, 1920. He was not recognized by France or Britain and his rule collapsed ending on July 25, 1920 when the region became a French mandate. Faisal was instead given the throne of Iraq.

On occasion the rulers of the Seleucid Empire are referred to as kings of Syria.
