List of subnational monarchs

This is a list of currently reigning constituent monarchs, including traditional rulers and governing constitutional monarchs. Each monarch listed below reigns over a legally recognised dominion, but in most cases possess little or no sovereign governing power. Their titles, however, are recognised by the state. Entries are listed beside their respective dominions, and are grouped by country.

Each major atoll in the Cook Islands has a number of arikis, ceremonial high chiefs who together form the Are Ariki, a parliamentary advisory body with up to 24 seats. The only domains not listed below are those of Manuae, on which current information is inadequate, and Penrhyn, whose chiefly line is extinct. Styles and names are listed in their conventional local form. In addition to the generic title of ariki, which is worn at the end of one's name, each chiefly line carries its own unique style, which is placed at the beginning. Thus, if the chief's name is "Henry" and his title is "Ngamaru", he is styled "Ngamaru Henry Ariki".

In Fiji, which became a colony of Great Britain in 1874, the British monarchs were historically bestowed the title Tui Viti, which translates as "King of Fiji" or "Paramount Chief of Fiji". The last holder of the title (from 6 February 1952) was Queen Elizabeth II, of the House of Windsor. The state became a republic in 1987, abolishing the title by establishing a new constitution. The former Great Council of Chiefs, however, still recognised Elizabeth II as Tui Viti, as the nation's traditional queen and its supreme tribal chief, despite no longer holding a constitutional office. Consequently, while Fiji remains a republic, a monarch or paramount chief is still recognised by traditional tribal politics. The Queen has made no official claim to the Tui Viti throne, although she has remained open to the possibility of a constitutional restoration of the monarchy.
