Tendürek (Turkish: Tendürek Dağı, Armenian: Թոնդրակ, Tondrak) is a shield volcano located in the Ağrı and Van provinces of eastern Turkey, close to the borders with Iran. The elongated volcano rises 1,800 m (5,906 ft) above the Doğubeyazıt plain, south of Mount Ararat. The last known eruption was a gas and ash eruption in 1855. The original, Armenian, name of the mountain was Tondrak; the area around Tondrak is known as the birthplace of the medieval Armenian Tondrakite Movement of the 950s, which based its ideology on the Paulician teaching.
