Kuchyňa Castle was a castle in the Little Carpathians near the municipality Kuchyňa in the Bratislava region, Slovakia. Only modest remains of certain parts of the castle are visible today. The ruins are situated at approximately 420 m above sea level. The castle ruins were discovered in the 1980s and are generally less well-known than those of other regional castles, such as Biely Kameň and Pajštún Castle. Nonetheless, the site remains a popular hiking destination.
