Amne Machin, Anyi Machen, or Anyê Maqên ("Grandfather Pomra") is the highest peak of a mountain range of the same name in the southeast of Qinghai province, China.

A part of the range around its highest peak has been declared a section of the Sanjiangyuan ("Sources of Three Rivers") National Nature Reserve.

The Northern Wei-era commentary on the Han-era River Classic stated that the mountain was the site where Yu the Great tamed the Yellow River and that it was considered part of Longxi Commandery, located 1740 li (724 km or 450 mi) from Kunlun Mountain and 5000 li (2,080 km or 1,290 mi) from the Luo.

The first European to describe the mountain was the British explorer Brigadier-General George Pereira on his expedition on foot from Peking to Lhasa of 1921–2, sometimes reckoned one of the great geographical discoveries of the twentieth century.

A 1930 article of the National Geographic estimated the peak elevation to 28,000 feet [8,500 m] according to the report of Joseph Rock, an American botanist and explorer who, despite death threats from the Golog Tibetans, had ventured to within 80 km of the mountain.
