Chumbi Valley (Tibetan: ཆུ་འབི, Wylie: chu vbi; Chinese: 春丕河谷; pinyin: Chūnpī Hégǔ) is a valley in Tibet at the intersection of India (Sikkim), Bhutan and China (Tibet) in the Himalayas. Two main passes between India and China open up here: the Nathu La Pass and Jelep La Pass. Administratively, the valley is in Yadong County of the Tibetan Autonomous Region.
The valley is at an altitude of 3,000 m (9,800 ft) and was at the forefront of the British military expedition of 1904 into Tibet. It was occupied by the British for about three years after the hostilities to secure Tibetan payment of indemnity. Contemporary documents show that the British continued the occupation of Chumbi Valley until February 8, 1908, after having received payment from China.
The valley blooms in spring. It enjoys a temperate climate.
The plant Pedicularis chumbica () is named after the valley.
