Galdor the Tall was the elder son of Hador of the Third House of the Edain, and the brother of Gundor and Glóredhel. He married Hareth daughter of Halmir, Chieftain of the Second House of the Edain. She bore him two sons, Húrin and Huor.

He succeeded his father as the Lord of Dor-lómin and Chieftain of the Third House when Hador was killed in the Dagor Bragollach.

Galdor was slain at Hithlum in a defence of Eithel Sirion from a further attack by Morgoth, seven years after the Dagor Bragollach. He was succeeded by Húrin.
