Axantur was a nobleman of Númenor.
Axantur was the son of Nolondil and the cousin of King Tar-Elendil. He had two other siblings: Yávien and Oromendil. He married an unnamed woman and had three children named Lindissë, Ardamir, and Cemendur. Little of Axantur's life is known but his descendants would enter into the ruling line and his great-grandson Hallacar would marry Tar-Ancalimë, the first Ruling Queen of Númenor.
