Bouchout Castle () is a castle in the Flemish town of Meise, Belgium. In the 12th century, this territory of the young Duchy of Brabant was strategically positioned between the County of Flanders and the Berthout family, lords of Grimbergen. Most likely, the first fortification was built by Wouter van Craaynem at the end of the Grimbergen Wars (1150–1170).
