Eggenberg Palace in Graz, is the most significant Baroque palace complex in the Austrian province of Styria. With its preserved accouterments, the extensive scenic gardens, as well as some special collections from the Universalmuseum Joanneum housed in the palace and surrounding park, Schloss Eggenberg ranks among the most valuable cultural treasures of Austria. Eggenberg Palace is situated at an elevation of 381 meters on the Western edge of the city. Its architectural design and the still visible imprint of centuries of history continue to bear witness to the vicissitude and patronage of the one-time mightiest dynasty in Styria, the House of Eggenberg.

The House of Eggenberg was the name of an influential Austrian noble family from Styria, who achieved princely rank in the 17th century. The family's last male heir died in 1717, bringing an end to the House of Eggenberg.
