The Yablonoi Mountains or Yablonovy Mountains (Russian: Яблоновый хребет, Buryat: Яабланай шэлэ нуруу, Yaablanai shele nuruu; Mongolian: Хэнтий нуруу, Khentii nuruu) are a mountain range, in Transbaikal (mainly in Zabaykalsky Krai, Khentii province), Siberia, Russia, Mongolia. The range is sparsely inhabited with most settlements engaged in mining. The area is especially rich in tin. The city of Chita lies between the Yablonoi Mountains to the west and the Chersky Range to the east.
The Trans-Siberian Railroad passes the mountains at Chita and runs parallel to the range before going through a tunnel to bypass the heights.
