Amasya is a city in northern Turkey and is the capital of Amasya Province, in the Black Sea Region.

The city of Amasya (Turkish pronunciation: [aˈmasja]), the Amaseia or Amasia of antiquity, stands in the mountains above the Black Sea coast, set apart from the rest of Anatolia in a narrow valley along the banks of the Yeşilırmak River. Although near the Black Sea, this area is high above the coast and has an inland climate, well-suited to growing apples, for which Amasya province, one of the provinces in north-central Anatolia Turkey, is famed. It was the home of the geographer Strabo and the birthplace of the 15th century scholar and physician Amirdovlat Amasiatsi. Located in a narrow cleft of the Yesilirmak (Iris) river, it has a history of 7,500 years which has left many traces still evident today.
