Fürstenfeld (Austrian German: [ˈfʏrstn̩fɛld]; Hungarian: Fölöstöm) is a small historic city in Styria, Austria.

The town has become quite famous in Austria and Germany because of the song by the same name by Styrian band S.T.S.. Fürstenfeld has a population of some 10,360 as of January 1st 2025.

Fürstenfeld was founded around 1170 as a defense against the Hungarians (the present Austrian state of Burgenland was part of Hungary until after World War I, so Fürstenfeld used to lie right on the border) and received its town charter in 1215.

Fürstenfeld is located in the lower Feistritz [ceb; de; sh; sv] valley near the Burgenland border.

The city`s central part sits on a river terrace two dozen meters above the valley floor.
