Mentioned in the Domesday Book Survey of 1086, Thorpe (Torp) was a settlement in the Hundred of Framland, Leicestershire. It had an estimate population of 48 households in 1086. The Tenant-in-chief, was held by Hugh de Grandmesnil, Sheriff of Leicestershire and Governor of Hampshire, who was richly rewarded by William the Conqueror for his part in the Norman Conquest of England.

From the 12th century, Thorp is known as Thorp Arnold, having taken the first name of its new owner, Arnold (or Ernauld, Latinised to Hernaldus) de Bois (French: "from the wood/forest") (Latinised to de Bosco ("from the wood/forest")), a vassal of the Earl of Leicester. His successors also used the first name Arnold. The death of Hernaldus de Bosco (Arnold de Bois) in 1255, a Warden of the Forest, is recorded by Matthew Paris in his Historia Anglorum (1250-1259), folio 170 verso. His arms were Argent, two bars and a canton gules.

Arnold I de Bois and his son Arnold II de Bois took an active part in the political life of England and Normandy. Arnold II supported Robert de Beaumont, 2nd Earl of Leicester and was rewarded by the earl with a grant of numerous manors in Leicestershire (including Thorpe Arnold, Brentingby, Evington, Humberstone and Elmesthorpe) and in Warwickshire (Clifton-on-Dunsmoor and Shrewley). The "de Bois" Book of Hours made at Oxford in 1325/30 for Hawise de Bois survives in the Pierpont Morgan Library in New York (MS-M700).

In the 17th century, Thorp Arnold was owned by sir Martin Lister, English politician, whose stepdaughter Frances Thornhurst became the mother of Sarah Churchill, Duchess of Marlborough.

John Towne (1711?–1791) was vicar of Thorpe Arnold before becoming the Archdeacon of Stow 5 September 1765 – 15 March 1791.
