Chomo Lonzo () is a mountain in Tibet, 5 km northeast of Makalu in the Mahalungur (Mohalingor) or Khumbu Himalayas. Alternate spellings of the same name include Chomolonzo, Chomolönzo, Chomo Lönzo, Jomolönzo, and Lhamalangcho.

Chomo-Lonzo has three distinct summits. The Southern, main peak (7804m) is joined via a ~ 7250m saddle to the Central peak (7565m), which is joined via a ~7050m saddle to a ~7200m North (or North West) peak.

While from Nepal the mountain is overpowered by nearby Makalu, the fifth-highest peak in the world, the three peaks are a very impressive and dominating sight from the Kangshung valley in Tibet. Chomo-Lonzo translates to “bird goddess” and from the East the mountain indeed brings to mind a 3 km high eagle with spread wings.

Climbing History

On October 30, 1954 the French climbers Jean Couzy and Lionel Terray made the first ascent of the main summit via the gently sloping SW ridge from the 7200m Sakietang La that separates Chomo Lonzo from Makalu.
