English: Chojnik Castle is a castle located above the town of Sobieszów, today part of Jelenia Góra in southwestern Poland. Its remains stand on top of the Chojnik Hill within the Karkonosze National Park, overlooking the Jelenia Góra Valley.

The building of the fortress dates back to the times of the Silesian Piasts and for most of its time was in the possession of the Schaffgotsch noble family. Today the semi-ruined stronghold is a tourist attraction and houses a hotel and a restaurant.

The castle of Chojnik was originally erected by the order of Duke [[w:en:Bolko_I_the_Strict]| Bolko I the Strict]] in 1292 at the site of a former hunting lodge built by his father Bolesław II the Bald. The fortress was meant to protect the borders of Bolko's Duchy of Jawor against the menacing Wenceslaus II of Bohemia. Bolko's grandson Bolko II the Small, the last independent Piast duke, started reconstruction of the castle in 1355.
