The Umba (Russian: Умба) is a river on the Kola Peninsula, Murmansk Oblast, Russia.

[1] The river's source is Lake Umbozero, 100 km northeast of Kandalaksha, located between the mountains of the Khibiny Massif and the Lovozero Tundras on the Kola Peninsula.

Its biggest tributary is the Vyala, which comes from Lake Vyalozero and joins the Umba 15 km before the outlet to the sea.

However, in recent years the number of salmon has dropped, as a result of poaching by the local population, caused by an unemployment rate of a staggering 90% in the municipal centre of Umba, and made worse by the fact that drivable roads go along the banks of the entire length of the river, making it easily accessible.

Semi-precious stones found in the Umba river are used for high quality, very rare jewelry.
