The Hill of Allen (Cnoc Alúine in Modern Irish, earlier Cnoc Almaine; also Hill of Almu ) is a volcanic hill situated in the west of County Kildare, Ireland, beside the village of Allen. According to Irish Mythology it was the seat of the hunter-warrior Fionn mac Cumhaill and the Fianna. The site is currently part-owned by Roadstone Dublin Limited and extensive quarrying has noticeably changed the profile of the hill.
