George McCoy is a British writer best known for producing McCoy's British Massage Parlour Guide, a series of guidebooks to establishments and women in Britain that provide sexual services.

The term massage parlour is used in the title of the books because the term massage is commonly used in Britain to euphemistically advertise sex work, soliciting prostitution being illegal in the country. McCoy has also written several other guides to sexual services in Britain and appeared in the media to discuss the country's sex industry.
