Forlindon was a name for the northern part of Lindon, north of the Gulf of Lune and west of the Blue Mountains. The land was traversed by a river which ended on the northern shore of the Gulf; the haven of Forlond was built there, on its mouths. Off its north-western coasts stood the island of Himring, where Maedhros's fortress had once stood.
Prior to the Great Battle the land of Lindon had been part of Ossiriand; afterwards the remnant was called Lindon, split into Forlindon and Harlindon by the newly created Gulf of Lune.
Gil-Galad lived in Forlindon in the Second Age.
