The Khastakh or Tuora-Yuryakh (Russian: Хастах; Yakut: Хаастаах, Xaastaax) is a river in the Sakha Republic (Yakutia), Russia. It is one of the two tributaries giving origin to the Indigirka. The river has a length of 251 kilometres (156 mi) and a drainage basin area of 10,500 square kilometres (4,100 sq mi). The upper stretch of its course is also known as Khalkan.

The river flows south of the Arctic Circle, across desolate tundra territories of the Oymyakonsky District marked by mountainous terrain and permafrost.
