The Derbeke (Russian: Дербеке; Yakut: Дэрбэкэ) is a river in the Republic of Sakha in Russia.
[1] It is an excellent river for boating, but it flows in an area without permanent population.
It heads roughly north and northeast, leaving the Verkhoyansk mountains, and meandering slowly across a swampy area in the Yana Plateau with numerous lakes, including Emanda (Yakut: Эмандьа).
[3] The river gains speed again in its lower course at the feet of the southeastern side of the Nelgesin Range when it flows through a narrow mountain valley.
Finally it joins the Adycha upstream from the Nelgese, the largest tributary.
