Branč Castle (Slovak: Branč Hrad) is a castle located in the village of Branč in the Trnava Region of Slovakia. The castle is situated on a hill that rises to an elevation of 475 meters above the village of Podbranč, close to the town of Senica in the Trnava Region of Slovakia.
Branč Castle was part of a network of frontier castles that ensured the safety of the routes leading from Moravia to the Carpathian passes. Constructed in the 13th century, it served as the administrative center for a large estate. By the end of the 17th century, the castle was destroyed by fire and subsequently fell into disrepair. Today, only the remnants of the walls of various buildings and some sections of the lower castle remain.
