The following is a list of the twenty-five Rulers of Númenor, an island realm in J. R. R. Tolkien's fictional universe. The Kings of Númenor were Dúnedain men who ruled the kingdom of Númenor. Númenor had twenty-five official rulers, of which there were twenty-two male rulers, and three female rulers. There was also one usurper (Herulcalmo).
A list of the rulers of the fictional island of Númenor, ordered by the fictional chronology of their reign. Many of the rulers have two names: Those beginning with "Tar-" prefix are titles in Quenya, a fictional elvish language, and those with the "Ar-" prefix are titles in Adûnaic, a fictional language of men. This usage does not represent the species of the ruler; all the figures below are Edain, or humans. Unless specified otherwise, all numbers are dates in the fictional Second age of Middle Earth. Figures marked with an asterisk were functionally or symbolically not recognized as rulers in the historical lore of Middle Earth.
Elros Tar-Minyatur (Y.S. 532–S.A. 442, r. S.A. 32–442) was one of the Half-elven of Middle-earth who chose to become a mortal man, and was later crowned the first High King of Númenor. He was born in year 532 of the First Age to Eärendil and Elwing.
Elros's name may mean "Elf of the Spray" based on a tale from his early childhood. Maedhros and Maglor, in an effort to wrest the Silmaril from Elwing and her people, attacked the settlement at the Mouths of Sirion, slaying many and driving Elwing over the sea. After the battle they found her children, Elros and his twin brother, Elrond, and taking pity on them, they raised them as their foster-children as an act of repentance. They later left them to be found in a cave where Elros was playing in a waterfall at the entrance and his brother was hiding in the back of the cave. Thus he was named "Elf of the Spray". In The Silmarillion, Christopher Tolkien interprets Elros as meaning "Star-foam".
