The Firnley Islands (Russian: острова Фирнлея; Ostrova Firnleya, Nynorsk: Firnleyøyane) is a group of three small islands covered with tundra vegetation and with scattered stones on their shores. They lie in the Kara Sea, close to the bleak coast of Siberia's Taymyr Peninsula, not far east of the Nordenskjold Archipelago. These islands lie about 35 km from the continental shore.

The Firnley Islands were named by Fridtjof Nansen after Thomas Fearnley^?, a Norwegian merchant who was one of the main financiers of the Fram expedition. They were also explored later by the Arctic Ocean Hydrographic Expedition.^[1]

The Firnley Islands are covering the entrance to the Vilkitsky Strait from the west. They are all relatively small islands, Dlinnyy, the largest of the group, is only about 5 km in length.

The sea surrounding the islands is covered with fast ice in the winter, which is long and bitter, and the climate is exceptionally severe. The surrounding sea is obstructed by pack ice even in the summer, so that these islands are connected with the mainland for most of the year.^[2]

This island group belongs to the Krasnoyarsk Krai administrative division of the Russian Federation. It is also part of the Great Arctic State Nature Reserve, the largest nature reserve of Russia.^[3]
