The Aktash (Russian: Акташ) is a river in the Kasbek and Khasavyurt districts of the Republic of Daghestan in Caucasian Russia.

Aktash derives from the Turkic ak- ("white") and taş ("stone").

The Don Cossacks arrived under Andrei Shadrin in the late 1570s, founding Andreyevo (present-day Endirey).

The mountainous area of the river was depopulated in 1877 by the Russian Adjutant-General Svistunov to prevent possible uprisings in support of Alibek Haji.

[3] Diversion of the river for irrigation now means that it usually does not reach the Caspian Sea during the summer months.
