The earliest chief city of the great island kingdom of Númenor which, during the Second Age, was found in the middle of Belegaer, the Great Sea.

Andúnië was a haven in the area of Andustar, the westernmost part of Númenor, and its name means "sunset."

The people who made their home there were called the Faithful for they remained true to the Eldar and the Valar during the darkening of Númenor before the downfall of the great island.
