This is a list of the Rulers of Númenor, a fictional realm by J. R. R. Tolkien. All told, there were twenty-five rulers of Númenor, beginning with Elros Tar-Minyatur and ending with Ar-Pharazôn.
MírielAr-Zimraphel (She was the rightful Queen, but was forced to wed Ar-Pharazon who took her throne)
Ar-Pharazôn the Golden Tar-Calion, last King of Númenor
The line of Kings was broken here, but the rightful rule continued through the Lords of Andúnië and the Dúnedain.
1: Tar-Ardamin does not appear in the list in the Lord of the Rings, but he does appear in the Unfinished Tales. In LOTR, Tar-Calmacil was followed by Ar-Adûnakhôr. His name was apparently dropped by error.
