The Elgi Plateau (Russian: Эльгинское плоскогорье;[2] Yakut: Эльгэ хаптал хайалаах сир) is a plateau in the Sakha Republic, Far Eastern Federal District, Russian Federation.

The area is named after the Elgi River, a left tributary of the Indigirka.

Dome-shaped peaks rise between the interfluves, where there are areas of small lakes and moorland.

The highest point of the Elgi Plateau is 1,590 metres (5,220 ft) high Tuoydakh Peak.

[5] Forests of larch taiga generally cover the flat areas and lower slopes, and in the higher elevations Siberian pine, giving way to alpine tundra in the mountaintops.
