Herz-Jesu-Kirche, Catholic church in Neumühl district, Duisburg, Germany.

The Herz-Jesu-Kirche is a historicist church in the Schmidthorst part of Neumühl, Duisburg, built 1912–1913. Its three-aisled nave seats about 500 people, and its two copper-clad towers, which give it the nickname Schmidthorster Dom, make it the only Duisburg church with two complete towers and spires. The plastered facades are divided by natural-stone elements, and the forms are mainly Neo-Gothic and Neo-Romanesque with Carolingian details on the towers.

Built 1912–1913 in Historicist style for the Herz Jesu parish, the church was financed partly by the Neumühl colliery, which gave 15,000 marks and supplied 8 million bricks. Bombed on 14 October 1944, it was patched up in 1945–46, re-roofed in 1952–53 and renovated in 1958, 1976 and 2002. Since 2015 it has been part of the St. Johann parish.

Locals call the church "Schmidthorster Dom" after the Schmidthorst district, and its two copper-clad towers make it Neumühl's landmark. Since 2015 it has been a parish church within the large St. Johann parish, covering the former St. Martin and Herz Jesu parishes. Its good acoustics make it a venue for concerts.

The church stands in Schmidthorst, part of Neumühl in Duisburg's Hamborn district, and is listed as monument number 11 in the Hamborn register. Its good acoustics make it a venue for concerts, so check local listings for event dates. The Kirchbauverein Herz-Jesu looks after restoration and upkeep and can be contacted about visits.

The church is nicknamed the "Schmidthorster Dom" because of its two copper-clad towers, and it is the only church in Duisburg with two complete towers topped by spires; St. Ewaldi in Laar lost the spire of its north tower after wartime damage and never rebuilt it.
