Nyergesújfalu (German: Neudorf; Latin: Crumerum) is a town in Komárom-Esztergom County, Hungary, in the Central Transdanubia region.

In the late 18th century Maria Theresa of Austria recruited German farmers to immigrate to the Danube Valley in order to repopulate it and revive agriculture.

The Germans came mostly from southern principalities and were Catholic; they were allowed to keep their language and religion, and established predominantly German-speaking towns.

The church still standing in the middle of Nyergesujfalu was finished in baroque style in 1770, on land granted to its founders by Empress Maria Theresa of Austria.

Following World War II, many ethnic Germans were expelled from Hungary and other parts of eastern Europe, as Nazi leader Adolf Hitler had used them as an excuse for warfare.

He had said he wanted to reunite ethnic Germans throughout Europe, under the rule of Germany, although these and others in Hungary had lived as Hungarians for more than 200 years.
