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 because of its well-preserved Gothic, Renaissance and Baroque architecture.

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.
