Ickworth House is a country house at Ickworth, near Bury St Edmunds in Suffolk, England. It is a neoclassical building set in parkland. The house was the residence of the Marquesses of Bristol until 1998; the house was given to the National Trust in 1956, but between then and 1998 the marquesses leased the east wing.
