Ozalj Castle is a historic fortress overlooking the Kupa River in the town of Ozalj, central Croatia.

First mentioned in 1244, it began as a medieval stronghold and later developed into a castle, becoming one of the country's most important noble residences. The castle is closely associated with the powerful Frankopan and Zrinski families, who played major roles in Croatian political and cultural history.

It is particularly remembered as a key site connected to the Zrinski–Frankopan conspiracy, a significant event in the 17th century. Today, Ozalj Castle is one of Croatia’s best-known historic landmarks. It houses a museum and library, preserves centuries of architectural development, and offers stunning views of the river valley and surrounding countryside.
