Raby Castle is a medieval castle located near Staindrop in County Durham, England, among 200 acres (810,000 m2) of deer park. It was built by John Neville, 3rd Baron Neville de Raby, between approximately 1367 and 1390. Cecily Neville, the mother of the Kings Edward IV and Richard III, was born here. After Charles Neville, 6th Earl of Westmorland, led the failed Rising of the North in favour of Mary, Queen of Scots in 1569 Raby Castle was taken into royal custody. Sir Henry Vane the Elder purchased Raby Castle in 1626 and neighbouring Barnard Castle from the Crown, and the Earls of Darlington and Dukes of Cleveland added a Gothic-style entrance hall and octagonal drawing room. From 1833 to 1891 they were the Dukes of Cleveland and they retain the title of Lord Barnard. Extensive alterations were carried out in the 17th and 18th centuries. It is famed for both its size and its art, including works by old masters and portraits. After 1733 it was frequented from his young age of eleven by the poet Christopher Smart, who eloped briefly at the age of thirteen with Anne Vane, daughter of Henry Vane, who succeeded to the Barnard title. It is a Grade I listed building and open to the public on a seasonal basis.

Cecily Neville was an English noblewoman, the wife of Richard, Duke of York (1411–1460), and the mother of two kings of England—Edward IV and Richard III. Cecily Neville was known as "the Rose of Raby", because she was born at Raby Castle in Durham, and "Proud Cis", because of her pride and a temper that went with it, although she was also known for her piety. She herself signed her name "Cecylle".
