The Pskem Mountain Range (, Pskemskiy Khrebet) or Piskom Mountains, is a mountain range located within the west Tien Shan range of Central Asia, and is a natural border between Kyrgyzstan and Uzbekistan. It extends over 160 km from north-east to south-west in the extreme north-eastern finger of Uzbekistan's Tashkent Region. The range is a water divide between the Pskem river to the north and the Chandalash, Chatkal, and Koʻksu rivers to the south. The highest elevations are attained in the north-east of the range: Mount Adelung (4301 m) and Mount Beshtor (4299 m). The river Pskem flows through the mountains on its way to Lake Charvak.
