A kraj (plural: kraje) is the highest-level administrative unit in the Czech Republic and the Slovak Republic. For lack of other English expressions, the Slavic term is often translated as "province", "region", or "territory", although it actually approximately means "(part of) country", or "(part of) countryside". A kraj is subdivided into okresy ("counties").
