Corvin Castle, also known as Hunyadi Castle (Romanian: Castelul Huniazilor or Castelul Corvinilor) is a Gothic-Renaissance castle in Hunedoara, Romania.

It is one of the largest castles in Europe and figures in lists of the Seven Wonders of Romania.

Built in a Renaissance-Gothic style and constructed over the site of an older fortification on a rock above the smaller Zlaști River, the castle is a large and imposing structure with tall towers, bastions, an inner courtyard, diversely coloured roofs, and myriad windows and balconies adorned with stone carvings.

The castle also features a double wall for enhanced fortification and is flanked by both rectangular and circular towers, an architectural innovation for the period's Transylvanian architecture.

Some of the towers (the Capistrano Tower, the Deserted Tower and the Drummers' Tower) were used as prisons. The Buzdugan Tower (a type of mace after which it was named) was solely built for defensive purposes and it had its exterior decorated with geometric motifs. The rectangular shaped towers have large openings to accommodate larger weapons.
