Choustníkovo Hradiště (German: Gradlitz) is a market town in Trutnov District in the Hradec Králové Region of the Czech Republic.

The village was named after the local castle (hradiště), owned by Heřmaň of Choustník.

In 1645, during the Thirty Years' War, the castle was destroyed by the Swedish army led by Lennart Torstensson.

The roof was repaired in 1754 and the premises then served as a granary, but at the turn of the 18th and 19th centuries, the castle quickly fell into disrepair.

The remains of the castle and its walls began to be demolished at that time, and the stone was used to build houses in the market town.
