Milarepa's Cave or Namkading Cave is a cave where the Tibetan Buddhist philosopher, and Vajrayana Mahasiddha, Milarepa spent many years of his life in the eleventh century. It is located 11 kilometres (7 mi) north of the town of Nyalam at Gangka village. It is on the slope below the China–Nepal Friendship Highway and above the Matsang river in Nyalam County, Tibet.

Jetsun Milarepa was a Tibetan siddha, who was famously known as a murderer when he was a young man, before turning to Buddhism and becoming a highly accomplished Buddhist disciple. He is generally considered one of Tibet's most famous yogis and spiritual poets, whose teachings are known among several schools of Tibetan Buddhism. He was a student of Marpa Lotsawa, and a major figure in the history of the Kagyu school of Tibetan Buddhism. He is also famous for the feat of climbing Mount Kailash.
