The Danube Swabians is a collective term for the ethnic German-speaking population who lived in Kingdom of Hungary of east-central Europe, especially in the Danube River valley, first in the 12th century, and in greater numbers in the 17th and 18th centuries. Most were descended from earlier 18th-century Swabian settlers from Upper Swabia, the Swabian Jura, northern Lake Constance, the upper Danube, the Swabian-Franconian Forest, the Southern Black Forest and the Principality of Fürstenberg, followed by Hessians, Bavarians, Franconians and Lorrainers recruited by Austria to repopulate the area and restore agriculture after the expulsion of the Ottoman Empire. They were able to keep their language and religion and initially developed strongly German communities in the region with German folklore.

The Satu Mare Swabians or Sathmar Swabians are a German ethnic group in the Satu Mare region of Romania. Romanian Germans, they are one of the various Danube Swabian subgroups that are actually Swabian in heritage, and their dialect, Sathmar Swabian, is similar to the other varieties of the Swabian German dialect.
