Ochtinská Aragonite Cave (Slovak: Ochtinská aragonitová jaskyňa, Hungarian: Martonházi-aragonitbarlang) is a unique aragonite cave situated in southern Slovakia, near Rožňava. Although only 300 m long, it is famous for its rare aragonite formations. Along with other caves of the Slovak Karst, it is included in the UNESCO World Heritage list as a component of Caves of Aggtelek Karst and Slovak Karst site, because of its diversity of aragonite formations and testimony to the cave-forming geologic processes.
