Delroy Easton Grant (born 3 September 1957) is a Jamaican-born British convicted serial rapist who carried out a series of offences of burglary, rape and sexual assault between October 1992 and May 2009 in the South East London area of England. Grant, also known as the Minstead Rapist and latterly the Night Stalker, is thought to have been active since 1990. He had a distinctive modus operandi, preying primarily on elderly women who lived alone. He is suspected of over 100 offences from 1990 to 2009.

In 1998, the Metropolitan Police launched the dedicated Operation Minstead team to investigate the crimes, based at Lewisham police station. (The name was chosen from an alphabetical list of English villages, the method of operational naming in use at the time). As of 2009, the operation was the largest and most complex rape investigation ever undertaken by the Metropolitan Police.

On 24 March 2011, Grant was found guilty of 22 offences. The following day he was given four life sentences and ordered to serve a minimum of 27 years in prison.

Operation Minstead was dramatised in the second series of the British TV show Manhunt, based on the memoirs of former Detective Chief Inspector Colin Sutton and was first shown in 2021.
