Whympston (anciently Wimpstone, Wymondston, Wimston, Wymston, etc), in the parish of Modbury in Devon, England, is a historic manor. In the 12th century it became the earliest English seat of the prominent Norman family of Fortescue, influential in British and West Country history, which survives today as Earl Fortescue, seated at Ebrington in Gloucestershire, but until recently seated at Castle Hill and Weare Giffard in Devon.
