The Timpton (Russian: Тимптон; Yakut: Төмтөөн) is a river in Sakha Republic (Yakutia), Russia. It is a right tributary of the Aldan River of the Lena basin. It has a length of 644 kilometres (400 mi) and a drainage basin area of 44,400 square kilometres (17,100 mi2). There are no settlements near its banks except for Nagorny village. The Timpton is crossed by the A360 Lena Highway and coal is mined in the river basin. Up to the present the Timpton is in a relative pristine condition, being a favorite destination for rafting and kayaking, but construction of the Nizhne-Timpton hydroelectric power station, approved in 2009, is planned on the river course in the future. Grayling, whitefish, taimen, rudd, perch and lenok are found in the waters of the river.
