The Chola Mountains, also romanized as the Trola Mountains, are a northern subrange of the Shaluli Mountains in western Sichuan Province，China. The mountains were once at the centre of the Kingdom of Derge and many remnant Tibetan Buddhist monasteries can be found in the mountain range's valleys.

The Chinese transliteration of the Chola Mountains is Que Er Shan (simplified Chinese: 雀儿山; traditional Chinese: 雀兒山; pinyin: Què'ér Shān). The Chola Mountains are named after the primary pass crossing the range, Cho La or Tro La. Cho La in Tibetan means Lake Pass. However, others claim, Chola is just another name for snow mountain, given by local Tibetans. Due to the Chinese transliteration of the mountains into Què'ér and its common usage on official maps, the mountain range is sometimes mistakenly translated into "Sparrow Mountains" or "Bird Mountains".

Located in the eastern Tibetan Plateau, the Chola Mountains are a result of uplift caused during the Indian subcontinent's collision with the Eurasian Plate. The Chola Mountains lie on the northeastern edge of a semi-independent tectonic block as part of the greater Eurasian Plate. The mountains range's abrupt northeastern edge is formed by the Ganzi segment of the Xianshuihe Fault where two blocks of the tectonic plate are experiencing strike-slip movement under stress.
