Posavina (Serbian Cyrillic: Посавина) is a geographical region that stretches along the Sava river, encompassing only the inner areas of the Sava river basin, that are adjacent or near to the Sava river itself, namely catch region spanning from the Julian Alps in the northwest to the confluence with the Danube in the southeast. It passes through several countries of former Yugoslavia, namely Slovenia, Croatia, Bosnia and Herzegovina and Serbia. In Slovene, the term Posavina is not used to describe the parts of Slovenia that lie by the Sava river. Instead, the terms Posavje, Zasavje and Zgornjesavska dolina are used (however, the parts of Slovenia between Litija and Bled, as well as Bohinj, are generally not defined by their proximity to the Sava river in Slovenian geographical nomenclature).
