Jasenovac Monastery, Serbian Orthodox monastery in Jasenovac, Croatia.

Jasenovac Monastery is a Serbian Orthodox monastery dedicated to the Nativity of St. John the Baptist and the seat of the Eparchy of Slavonia. Its church was built in 1775; a garage that formed part of the church later belonged to the Jasenovac concentration camp. The church was restored and consecrated on 2 September 1984, and in 2000 Bishop Sava Jurić proclaimed it a monastery.

The monastery was originally built in 1775 and experienced major destruction followed by rebuilding during the 20th century conflicts. Its multiple reconstructions reflect the complex history of the region and the resilience of those who maintained it.

The monastery is dedicated to the Nativity of St. John the Baptist and belongs to the Eparchy of Pakrac-Slavonia of the Serbian Orthodox Church. Under Bishop Sava Jurić of Slavonia it served as the seat of the Eparchy of Slavonia, and in 2000 he proclaimed the church a monastery. Its abbot was Amfilohije Živković.

The monastery stands in Jasenovac, Croatia, near the confluence of the Una and Sava rivers, at coordinates 45.27167, 16.91194. It belongs to the Eparchy of Pakračko-slavonska of the Serbian Orthodox Church and was the seat of the Eparchy of Slavonia during the time of Bishop Sava Jurić. The church is dedicated to the Nativity of St. John the Baptist.

The church that preceded the monastery was demolished in 1941 by the first inmates of the Jasenovac concentration camp, and a garage belonging to it was incorporated into the camp. The church was rebuilt and consecrated on 2 September 1984, damaged again in 1991, desecrated during Operation Flash in May 1995, and restored in 2000, when Bishop Sava Jurić declared it a monastery.
