Freudenstein Castle () is located on the Schloßplatz ("Castle Square") on the edge of the town centre of Freiberg in the German state of Saxony. Its history is closely linked to the House of Wettin. After several connversions the castle is now a stately home with four wings comprising these buildings: the Langes Haus, Neues Haus, Kirchenflügel, Großer Turm und Schmales Haus ("Long House", "New House", "Church Wing", "Great Tower" and "Narrow House").
