The Kondyor Massif (Russian: горы Кондёр) or Konder[1] is a circular intrusion of igneous rock,[2] about 8 kilometres (5 mi) in diameter. It is located in Khabarovsk Krai, Russia, c. 600 km (373 mi) west-southwest of Okhotsk, or c. 570 km (354 mi) south-east of Yakutsk. It is reached from Yakutsk by road via Amga. It is an important source of platinum.

The Kondyor Massif stands as a textbook example of a ring intrusion, renowned for its remarkable geometric circularity and distinct ridge-and-depression topography. It serves as a global reference site for the study of alkaline-ultramafic magmatism and associated platinum-group element mineralization.{{citation needed|date=November 2025} Since 1984, Artel Starateley "Amur" (part of the Russian Platinum group) has developed this alluvial platinum deposit.
