Newbold Revel is an 18th-century country house in the village of Stretton-under-Fosse, Warwickshire, England. It is now used by HM Prison Service as a training college and is a Grade II* listed building.
The house was built in 1716 for Sir Fulwar Skipwith, 2nd Baronet and was constructed of brick in three storeys to an H-shaped plan with an 11-bay frontage. In the late 19th century the ground floor was extended forwards.
The Manor of Newbold Revel, originally Fenny Newbold, was acquired by the Revel family around 1235. It descended to Sir John Revel, MP and on his death with no son passed to his daughter Alice, who had married Esquire John Malory of Winwick, Northamptonshire. Their son was Sir Thomas Malory, author of le Morte d'Arthur and MP for Warwickshire from 1443 to circa 1446. His great-grandson Nicholas sold the property, after which it passed through a succession of private hands, including those of the builder of the present house, Sir Fulwar Skipwith. 
The estate was purchased in 1863 by Edward Wood and descended to his grandson before being acquired in 1898 by Colonel Heath, a Staffordshire brick manufacturer, and in 1911 by the Austrian banker, Leo Bonn. After Bonn's death in 1929 the property passed in 1931 to the Seventh-day Adventists for use as a missionary training college but was requisitioned in 1942 for use as an agent training establishment during World War II. It was an RAF Y-station Secret Intelligence Service and German telephony communications base. After the war it was purchased by the Sisters of Charity of St. Paul as a Catholic teacher training college, and sold in 1978 to British Telecom. 
In 1985 it was taken over by the Prison Service for its current use as the Prison Service College.
