The Timpton (Russian: Тимптон; Yakut: Төмтөөн) is a river in Sakha Republic (Yakutia), Russia.

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.

Its source is located on the northern slopes of the Stanovoy Range, at the southern limit of Yakutia, near the Amur Oblast border.

It crosses the foothills of the Aldan Highlands and its valley marks the western limit of the Sunnagyn Range.
