Croatian National Theatre

Croatian National Theatre (Hrvatsko narodno kazalište) is the official name of several state-funded theatre houses in Croatia. Each one is commonly referred to by the Croatian-language initialism HNK. The four theatre houses in biggest cities (Zagreb, Split, Rijeka and Osijek) are considered premier theatre and opera houses in the country. In addition, there are three other smaller theatres carrying that name in Croatia (in Šibenik, Varaždin and Zadar) and one in Bosnia and Herzegovina (in Mostar).
