Cobham Hall is a historic manor house in the county of Kent, England. The grade I listed building is one of the largest and most important houses in Kent, re-built in the Tudor style by William Brooke, 10th Baron Cobham. The central block was rebuilt 1672–82 by Charles Stewart, 3rd Duke of Richmond, 6th Duke of Lennox.
Today the building houses Cobham Hall School, a private boarding school for girls, established there in 1962, which retains 150 acres of the ancient estate.
