Hylton Castle is a stone castle in the North Hylton area of Sunderland, Tyne and Wear, England. Originally built from wood by the Hilton family shortly after the Norman Conquest in 1066, it was later rebuilt in stone in the late 14th to early 15th century. The castle underwent major changes to its interior and exterior in the 18th century and it remained the principal seat of the Hylton family until the death of the last Baron in 1746.
