Tolisa franciscan monastery, Franciscan monastery and National Monument in Tolisa, Bosnia and Herzegovina.

Tolisa Franciscan Monastery consists of the Church of the Assumption of the Blessed Virgin Mary, old and new monastery buildings, and a movable heritage collection. The church, measuring 25.60 by 56 metres, is a three-nave basilica with two brick bell towers 56 metres tall, built in Romanesque style after the old Jesuit church in Osijek. Its long axis runs west-east, offset about 14 degrees north.

Fra Martin Nedić began building the monastery in 1864. Tolisa was declared a residence in 1869 and a monastery in 1876. The Church of the Assumption was completed in 1881 by builder Đuro Eichorn of Osijek, modelled on Osijek's old Jesuit church. Architect Josip Vancaš rebuilt the interior in 1911, and the complex was damaged during the 1992–1995 war.

The monastery serves as a living religious community where Franciscan monks continue their spiritual practices and daily life today. The space reflects their commitment to prayer, study, and service, which shapes how the grounds are organized and used by those who live there.

Visitors can explore the grounds, but should be aware this is an active religious community where monks live and work. The best time to visit is outside of main prayer hours to avoid interrupting the daily rhythm of the community.

The monastery library keeps the original 1863 firman of Sultan Abdul Aziz, measuring 78 by 54 cm, which authorised construction of the new church. Its numismatic collection holds 974 coins issued by rulers who passed through the Posavina region, from Greek and Roman to Ottoman and Venetian.
