Český Krumlov (Czech pronunciation: [ˈtʃɛskiː ˈkrumlof] (listen); German: Krumau, German pronunciation: [kʁʊˈmaʊ̯] (listen), or Böhmisch Krumau) is a town in the South Bohemian Region of the Czech Republic. Its historic centre, centred around the Český Krumlov Castle, has been a designated UNESCO World Heritage Site since 1992 and was given this status along with the historic Prague castle district.

Krumlov has its origin in Middle High German Krumme Aue, which can be translated as crooked meadow, after a bend of the Vltava. The town's name begins with Český ("Bohemian") to differentiate it from Moravský Krumlov in south Moravia.
