Čeklís Castle was a medieval fortification near Bernolákovo in the Bratislava region, Slovakia. The castle was most likely built in the 13th century. It was destroyed and abandoned in the 16th century. Nowadays only a part of the perimeter wall, about 32 m long and situated on the edge of the ridge, has been preserved from the castle above ground level. A water tower was built on top of the castle remains in 1905. The tower was styled to fit the historical environment but is materially completely separate from the Čeklís Castle.
