{{Monarchism}}
Currently ({{as of|2023|lc=y}}),<!--but note death of [[Bhumibol Adulyadej]] in October 2016--> seventeen kings are recognized as the heads of state of [[sovereign state]]s (i.e. English ''king'' is used as official translation of the respective native titles held by the monarchs).

Most of these are heads of state of [[constitutional monarchy|constitutional monarchies]]; kings ruling over [[absolute monarchy|absolute monarchies]] are the [[King of Saudi Arabia]], the [[King of Bahrain]] and the [[King of Eswatini]].<ref>The distinction of the title of "king" from "sultan" or "emir" in oriental monarchies is largely stylistics; the  [[Sultanate of Oman]], the [[State of Qatar]], the [[State of Kuwait]] and the [[United Arab Emirates]] are also categorised as absolute monarchies.</ref>
