The Neuwerkskirche (pronounced [ˈnɔʏvɐksˌkɪʁçə], also Cruciskirche, "Cross Church") at the edge of the historical part of the city of Erfurt in Thuringia, Germany, is a Roman Catholic church building dating from the 15th century.

The Late Romanesque building stood in the new part of the city built in 1166 named Auf dem neuen Werke ("By the new facility"), from which its name is derived.

[2] The church with the patronage of the Holy Cross (Latin: sanctae crucis, hence Cruciskirche) belonged to the convent of the Augustinian nuns, the Neuwerkskloster.

In 1466–73, the present church was built in Late Gothic forms, which were then baroqueised between 1731 and 1735; on 25 September 1735, it was consecrated by Bishop Gudenus.

It was restored and partially reconstructed in 2000–2003 by the organ-building company Alexander Schuke from Potsdam.
