Moreton House (formerly until 1821 Daddon House) is a grade II listed country house and former large estate near Bideford, North Devon, England. The house is about one mile west of the old centre of Bideford town, its entrance drive leading off the south side of the road between Bideford and the village of Abbotsham. It has in recent years become increasingly surrounded by the suburbs of Bideford, and in 2014 only 5 acres of the former parkland remain attached to the house. The estate is said anciently to have been the property of the famous Grenville family, lords of the Manor of Bideford, and of Stowe, Kilkhampton in Cornwall. It was later acquired by the Buck merchant family of Bideford, which rebuilt the house in 1760 and again in 1821.
In 1858 the Buck family changed its name to Stucley, in reference to a recent female ancestress and heiress. The now "Stucley" family, which had inherited other substantial residences at Hartland Abbey, Affeton and North Molton, sold Moreton House in 1956, after which it was occupied by Grenville College, a private school, which vacated the site in 2009. The house is a fine example of Georgian architecture and had at one time ornate gardens with two lakes, fountains, waterfalls and formal herbaceous borders. The house with five acres of land was offered for sale in 2014 for the surprisingly low price of £500,000. The house's former name is memorialised by an industrial estate called "Daddon Court" a short distance to the south of the house.
