克恩顿州（德语：Kärnten，斯洛文尼亚语：Koroška，英语：Carinthia），又译作“克恩滕州”或“卡林西亚州”，是奥地利最南面的一个州。

德语名称Kärnten出自凯尔特语“karantos”，意为友好的人，所以州名可以理解为“友善之地”。也有说法称州名来自居住在该州境内阿尔卑斯山地区的凯尔特人部落“Carni”，第三种说法称该名得自伊利里亚语“karant”，意为「岩石、峭壁」。

Carinthia (German:Kärnten, German pronunciation:[ˈkɛɐ̯ntn̩], Slovene:Koroška,  pronunciation , Croatian:Koruška, Italian:Carinzia, Hungarian:Karintia) is the southernmost Austrian state or Land. Situated within the Eastern Alps it is noted for its mountains and lakes. The main language is German. Its regional dialects belong to the Southern Bavarian group. Carinthian Slovene dialects, which predominated in the southern part of the region up to the first half of the 20th century, are now spoken by a small minority.
