Hradištko is a municipality and village in Prague-West District in the Central Bohemian Region of the Czech Republic.

The Štěchovice Reservoir, built on the Vltava, lies on the southern municipal border.

The first written mention of Hradištko is in a papal bull of Pope Clement V from 1310.

The owners of the village often changed until 1636, when Hradištko was purchased by the Strahov Monastery.

There was a fortress from 1571, which was rebuilt into the current simple Baroque castle in 1709.
