Ani Tsankhung Nunnery (Tibetan: ཨ་ནི་མཚམས་ཁུང, Wylie: A ni mtshams khung Chinese: 阿尼仓空寺; pinyin: Ā ní cāng kōng sì) is a nunnery of the Gelug school of Tibetan Buddhism in the city of Lhasa, Tibet Autonomous Region, China.

[5] The 7th century Tibetan king Songtsen Gampo used to meditate at a natural cave in this location, and recited prayers to reduce the danger of flooding by the Lhasa River.

[3] The Tibetan Living Buddha Samding Dorje Phagmo began her life as a Buddhist at the monastery.

[5] The Lama Pabongkhapa Déchen Nyingpo and Tampa Dhoedrak, throne holder of Ganden Monastery, enlarged the nunnery to its present size early in the 20th century.

[4] The nuns run an inexpensive outdoor restaurant, which is busy at lunch time, serving bowls of noodles and dumplings.
