Peter I Range, Peter the First Range[1] or Peter the Great Range (Russian: Хребет Пётра I or Хребет Пётра Первого) is a mountain range in Tajikistan, part of the Pamir Mountain System.

The range takes its name from Peter the Great (1672 – 1725).

Peter I Range is located in the south-east of Jirgatol district in Tajikistan's Region of Republican Subordination.

It forms a westerly extension of the northern Pamirs, separating the watersheds of the Surchob in the north and the Obikhingou river in the south.

The range stretches in a roughly east–west direction for about 200 km, connecting with the Academy of Sciences Range at its eastern end.
