The Yana-Indigirka Lowland (Russian: Яно-Индигирская низменность; Yakut: Дьааҥы - Индигир намтала, romanized: Câñı - İndigir namtala) is a large, low alluvial plain located in northern Siberia, Far Eastern Federal District, Russia.

[2] The Yana-Indigirka Lowland is roughly crescent-shaped, reaching a maximum width in its central part of 300 kilometers (190 mi).

[5] There are residual ridges of bedrock, up to 558 meters (1,831 ft) high, rising above the lowland, the northernmost of which is the Kondakov Plateau.

[1] The lowlands have a thermokarst ground, composed of various kinds of marine, river and lake sediments with a high content of fossil ice owing to the prevalence of permafrost.

the waters of rivers and lakes are rich in various species of fish, such as Siberian vendace, chir, muksun, nelma and omul.
