The Yana (Russian: Я́на, IPA: [ˈjanə]; Yakut: Дьааҥы, romanized: Câñı) is a river in Sakha in Russia, located between the Lena to the west and the Indigirka to the east.

The whole Yana basin is under continuous permafrost and most is larch woodland grading to tundra north of about 70°N, though trees extend into suitable microhabitats right to the delta.

[citation needed] The main tributaries of the Yana are the Adycha, Oldzho, Sartang and Abyrabyt from the right, and the Dulgalakh, Bytantay, Tykakh and Baky from the left.

[4] Evidence of modern human habitation was found in the delta at the Yana RHS (Rhinoceros Horn Site) as early as 32,000 years ago.

[5] In 1633–38 Ilya Perfilyev and Ivan Rebrov sailed down the Lena and east along the Arctic coast to the mouth of the Yana and reached the Indigirka estuary.
