Brougham Castle is a medieval building about south-east of Penrith, Cumbria, England. The castle was founded by Robert de Vieuxpont in the early 13th century. The site, near the confluence of the rivers Eamont and Lowther, had been chosen by the Romans for a Roman fort called Brocavum. The castle is scheduled as an Ancient Monument, along with the fort, as "Brougham Roman fort and Brougham Castle".
