Mount Ararat (, ARR-ə-rat; Armenian: Արարատ, romanized: Ararat), also known as Mount Ağrı (Turkish: Ağrı Dağı) or Masis (Armenian: Մասիս), is a snow-capped and dormant compound volcano in eastern Turkey. It consists of two major volcanic cones: Greater Ararat and Little Ararat. Greater Ararat is the highest peak in Turkey and the Armenian Highland with an elevation of 5,137 m (16,854 ft); Little Ararat's elevation is 3,896 m (12,782 ft). The Ararat massif is about 35 km (22 mi) wide at ground base. The first recorded efforts to reach Ararat's summit were made in the Middle Ages, and Friedrich Parrot, Khachatur Abovian, and four others made the first recorded ascent in 1829.

In Europe, the mountain has been called by the name Ararat since the Middle Ages, as it began to be identified with "mountains of Ararat" described in the Bible as the resting place of Noah's Ark, despite contention that Genesis 8:4 does not refer specifically to a Mount Ararat.

Despite lying outside the borders of modern Armenia, the mountain is the principal national symbol of Armenia and has been considered a sacred mountain by Armenians. It has featured prominently in Armenian literature and art and is an icon for Armenian irredentism. It is depicted on the coat of arms of Armenia along with Noah's Ark.
