Heiligenbrunn is a small settlement with less than 800 inhabitants (as of 2018) in Burgenland, in the Güssing district of Austria. The Hungarian name is Szentkút and the Croatian is Šenkut.

It was first mentioned in the written archives in the 12 century, and as each border area passed to different countries. Following the negotiations since the end of World War I, the territory was given to Austria and the newly created federal province of Burgenland.

The modern administrative structure was formed in 1971. by bringing together several independent communities. However, irrespective of the twists and turns in its history and development, Heiligenbrunn has succeeded in retaining the vision and spirit that is less and less common in today's globally dynamic world.
