Sannikov Land (Russian: Земля Санникова, Zemlya Sannikova) was a phantom island in the Arctic Ocean.

[1] In 1886, the Baltic German explorer in Russian service Baron Eduard von Toll reported observing the elusive land during an expedition to the New Siberian Islands.

Attempts to reach Sannikov Land, deemed to be beyond the De Long Islands, continued in 1902 while the Zarya was trapped in fast ice.

In November, Toll and three companions left the Zarya and travelled south on loose ice floes, away from Bennett Island, and vanished forever.

In 1973, a science fiction film based on Obruchev's book, called The Land of Sannikov, was released in the Soviet Union.
