克桑托斯（吕基亚语：Arñna；希腊语：Ξάνθος；拉丁语：Xanthus；土耳其语：Ksantos），是古代吕基亚的一个城市，遗址位于今土耳其安塔利亚省的奇尼克。当地的葬殡艺术遗址非常有代表性，它反映了吕基亚传统与希腊文化影响的交融，很多古老的碑文现在是研究印欧语系以及吕基亚人历史的重要参考。克桑托斯同时也是莱克伊亚地区最大的宗教中心和商业中心，这里在罗马时代和拜占庭帝国时代建造了很多非常重要的建筑物。

Xanthos (Lycian: Arñna, Greek:Ξάνθος, Latin: Xanthus, Turkish: Ksantos) was the name of a city in ancient Lycia, the site of present-day Kınık, Antalya Province, Turkey, and of the river on which the city is situated. The ruins of Xanthus are on the south slopes of a hill, the ancient acropolis, located on the northern outskirts of the modern city, on the left bank of the Xanthus, which flows beneath the hill. A single road, Xantos yolu, encircles the hill and runs through the ruins.
