Magadan Nature Reserve, Protected nature reserve in Magadan Region, Russia.

Magadan Nature Reserve spans four sectors covering approximately 883,817 hectares along the Sea of Okhotsk. The reserve includes coastal zones, mountainous terrain, forest areas, and islands that support diverse wildlife and plant species.

The idea of a reserve came from Alexei Petrovich Vas'kovsky (1911–1979) of the Institute of Biological Problems of the North, with groundwork starting in 1973. It was founded on 1 May 1982 by a decree of the Council of Ministers of the RSFSR and the Magadan regional executive committee, covering 883,817 hectares in four separate sectors. In 2004 BirdLife International classified it as an Important Bird Area, and since 2005 it has been a candidate for the UNESCO World Heritage List.

The reserve's name comes from the city of Magadan, where its central office is located, 100 to 650 km from the four sectors. The Kava-Chyolomdzha sector protects an untouched spawning ground for chum and coho salmon on the Chyolomdzha River, one of the largest on the northern Sea of Okhotsk coast. Spotted seals follow the salmon up the Tauy River, sometimes 150 km from the sea.

The reserve has no settlements or transport routes within its four sectors, and the administration is in Magadan, 100–650 km from the sites. Access is only by organised boat or river expeditions with special permits; arrange these through the reserve office in advance. The climate is monsoonal, with January averages below –25 °C and July averages of +12 to +15 °C.

The Yamsky sector's island group includes Matykil and Atykan plus three smaller rocks, Baran, Khatemalniu and Kokontse, lying 10–15 km off the Pyagina Peninsula. Matykil alone holds 12 seabird species totalling 4.7 million birds, among them horned puffins and spectacled guillemots. Fur seals and bearded seals also haul out at its eastern tip.
