Gwanaksan (Korean for Mt. Gwanak; 632 m) is a mountain in southern Seoul, South Korea. Portions lie in the Gwanak-gu and Geumcheon-gu districts of Seoul; other portions lie in the neighboring cities of Anyang and Gwacheon.The name gwanak means "hat-shaped peak," and refers to its gat-like profile. Thus Gwanaksan literally means "mountain of the hat-shaped peak." Currently it is referred to as "Gwanak," since san already contains the meaning of "mountain." Together with Songaksan in Kaesong, Gamaksan in Paju, Uaksan in Pocheon, and Hwaaksan in Gapyeong, Gwanaksan was long considered one of the five representative peaks of Gyeonggi-do (gyeonggi o-ak).
