The name Nuštar comes from monasterium, because a Benedictine monastery of the Holy Spirit existed there in 1263. The nobleman Nikola Berzeta acquired the estate in the 14th century, and in the 15th century it was owned by the Gorjanski family. A castle that was owned by the Khuen-Belassy family was expanded and had a church built within it in the 18th century. This church was renovated during the 19th century and the castle is now surrounded by a park. Ban of Croatia-Slavonia Károly Khuen-Héderváry spent most of his childhood at the estate.

Nuštar suffered major damage during the Croatian War of Independence, when it was surrounded by the rebel Serb forces and often shelled. When Vukovar fell in the Battle of Vukovar, Nuštar was the main extraction point for survivors and the village itself became surrounded from three directions. The parish church of the Holy Spirit suffered extensive damage in the war, which has since been repaired.
