埃特纳火山（意大利语：Etna），是欧洲著名的活火山，属层状火山。它位于意大利西西里岛东海岸的墨西拿和卡塔尼亚之间，是欧洲最高的活火山，海拔3326米，其高度随喷发活动而变化。埃特纳火山下部为一个巨大的盾形火山，上部为高约300米的火山渣锥，面积约1190平方公里，底部周长约140公里。由于埃特纳火山处于亚欧板块和非洲板块交汇处，一直活动频繁，其喷发史可以追溯到公元前1500年，迄今为止已喷发过200多次。2002年10月28日曾大规模喷发。

Mount Etna (pronunciation: /ˈɛtnə/; Italian:Etna [ˈɛtna] or Mongibello, Sicilian:Mungibeddu or â Muntagna, Latin:Aetna) is an active stratovolcano on the east coast of Sicily, Italy, in the Province of Catania, between Messina and Catania. It lies above the convergent plate margin between the African Plate and the Eurasian Plate. It is the tallest active volcano in Europe, currently 3,329 m (10,922 ft) high, though this varies with summit eruptions. It is the highest mountain in Italy south of the Alps. Etna covers an area of 1,190 km (459 sq mi) with a basal circumference of 140 km. This makes it by far the largest of the three active volcanoes in Italy, being about two and a half times the height of the next largest, Mount Vesuvius. Only Mount Teide in Tenerife surpasses it in the whole of the European–North-African region. In Greek Mythology, the deadly monster Typhon was trapped under this mountain by Zeus, the god of the sky and thunder and king of gods, and the forges of Hephaestus were said to also be located underneath it.
