Geomeun Oreum (Korean: 검은 오름; Hanja: 黑岳), popularly called Geum Oreum (금오름; 今岳) and alternately called Geumak (금악; 今岳),[1][2] is an oreum (small extinct volcano; parasitic cone) in Hallim, Jeju City, Jeju Province, South Korea.

"Geom" may also mean "god", suggesting that the oreum had an important local spiritual role.

[2] There is a caldera around 52 m (171 ft) deep[4] at the top of the mountain called Wangmae or Ammae (왕메; 암메).

[3][5][2] Amphibians live in this marshy area and have been affected by human activity at the top.

[6] Before 2009, livestock used to graze on the oreum; they were relocated in order to accommodate the safety of tourists.
