The koruna, or crown (sign: Kč; code: CZK, Czech: koruna česká), has been the currency of the Czech Republic since 1993. The koruna is one of the European Union's eight currencies, and the Czech Republic is legally bound to adopt the euro in the future.
The official name in Czech is koruna česká (plural koruny české, though the zero-grade genitive plural form korun českých is used on banknotes and coins of value 5 Kč or higher).
