Dykh-Tau or Dykhtau (Russian: Дыхтау, Karachay-Balkar: Дых тау that is derived from Turkic "dik dagh" which means Jagged Mount), is the second-highest mountain in Russia and Europe, standing at 5,205 m (17,077 ft) above sea level.

It is located in Kabardino-Balkaria, Russia; its peak standing about 5 km (3 mi) north of the border with Georgia.

Bezingi village may be reached from Nalchik in Kabardino-Balkaria with infrequent public transport, here a 4WD vehicle must be hired.

The first ascent in 1888 by Albert Mummery and Heinrich Zurfluh of Meiringen was a major achievement at the time.

Once a notch between Misses-Tau and Dykhtau is gained, the North Ridge is followed to the summit.
