Yevpatoria or Eupatoria is a city in Crimea, Ukraine. The first recorded settlement in the area, called Kerkinitis (Κερκινίτης), was built by Greek colonists around 500 BC. Along with the rest of Crimea, Kerkinitis was part of the dominions of Mithridates VI, King of Pontus, from whose cognomen, Eupator, the city's modern name derives.
From roughly the 7th through the 10th centuries AD Yevpatoriya was a Khazar settlement; its name in Khazar language was probably Güzliev (literally "beautiful house"). It was later subject to the Cumans (Kipchaks), the Mongols and the Crimean Khanate. During this period the city was called Kezlev by Crimean Tatars and Gözleve by Ottomans. The Russian medieval name Kozlov is a Russification of the Crimean Tatar name.
