The Gurk (German pronunciation: [ɡʊʁk] ⓘ; Slovene: Krka) is a river in the Austrian state of Carinthia, a left tributary of the Drava.

Its sources are two small cirque lakes, the Gurksee and the Torersee near Albeck and the Turracher Höhe Pass, a protected area since 1981.

It flows southwest to Ebene Reichenau and then turns eastwards running through Gnesau and the Gurktal valley to the market town of Gurk.

Near Straßburg it again turns to the south, enters the Klagenfurt basin, and flows into the Drava west of Völkermarkt.

Its tributaries include the Görtschitz [ceb; de; sl; sv], the Metnitz (left), and the Glan (right).
