The Castle of Boussu (Château de Boussu) in Boussu, Hainaut, Belgium, is a Renaissance estate that originated on a site used since Gallo-Roman times, with the first castle built in the 10th century and later owned by the Fontaine and Hénin-Liétard families.

The great castle that became famous was rebuilt in the 16th century under Jean V de Hénin-Liétard, first Count of Boussu, by the architect Jacques du Broeucq, and was admired by Charles V, the Holy Roman Emperor, who visited it in 1545. After centuries of war damage, the main building was largely ruined by the early 19th century and subsequently dismantled, leaving only the gatehouse (châtelet) and some underground remains, while the gatehouse later served as a Luftwaffe ammunition depot during World War II and was heavily damaged in 1944 before being restored from 2010 into a small museum and interpretation centre.

Today the site forms a 12‑hectare park with old trees, biodiversity, and a lapidary museum housed in the 16th‑century Gothic funerary chapel of the Lords of Boussu, which features rich Renaissance sculptures and is closely linked to the castle’s heritage. The listing castle complex and park, now managed as an archaeological and heritage site near Mons and the Grand Hornu, offers guided visits of the gatehouse, the chapel, and the gardens, making it a distinctive example of Renaissance architecture and noble memory in Wallonia.
