Latorica (, pronounced: Latoritsa;, translit.: Latorytsia) is a river in the watershed of the Danube. Its source is in the Ukrainian Carpathians (Eastern Carpathian Mountains), near the village Latirka. It flows from Ukraine (156.6 km) to Slovakia (31.4 km), 188 km in total and west through the towns of Svaliava, Mukachevo, Solomonovo, Chop and Veľké Kapušany. Its basin size is 7740 km2. Its confluence with the Ondava, in Zemplín, gives rise to the Bodrog river, itself a tributary of the Tisza. A part of its watershed (Latorica Protected Landscape Area, "Ramsar site No. 606", 44.05 km2) has been added to the Ramsar list of wetlands of international importance since 1993.

Etymology

It is interpreted differently: according to one hypothesis, it is a pre-Slavic noun, according to others it is related to Slavic, based on lat- "studeny" (meaning "cold river").
