The Tavna Monastery (Serbian: Манастир Тавна) is a Serbian Orthodox monastery located south of the city of Bijeljina in north-eastern Republika Srpska, Bosnia and Herzegovina. The date of its foundation is unknown.
Tavna was damaged in the first years of Ottoman rule, but was restored by the people. This was not the only time the monastery was damaged. It was damaged many times during the Ottoman period and also during World War II. Between 1941-45 Tavna was bombed by the Nazi-affiliated Croat Ustashe but was reconstructed after the war.
