Hatchards is an English bookshop claiming to be the oldest in the United Kingdom, founded on Piccadilly in 1797 by John Hatchard. After one move, it has been at the same location on Piccadilly next to Fortnum & Mason since 1801, and the two stores are also neighbours in St. Pancras railway station as of 2014. It has a reputation for attracting high-profile authors and holds three royal warrants granted by King Charles III, Queen Elizabeth II, and Prince Philip respectively.

Piccadilly is a road in the City of Westminster, London, England, to the south of Mayfair, between Hyde Park Corner in the west and Piccadilly Circus in the east. It is part of the A4 road that connects central London to Hammersmith, Earl's Court, Heathrow Airport and the M4 motorway westward. St James's is to the south of the eastern section, while the western section is built up only on the northern side. Piccadilly is just under 1 mile (1.6 km) in length, and it is one of the widest and straightest streets in central London.
