The Carlton Hotel was a luxury hotel in London that operated from 1899 to 1940. It was designed by the architect C. J. Phipps as part of a larger development that included the rebuilding of Her Majesty's Theatre, which is adjacent to the hotel site. The Carlton was originally run by the Swiss hotelier César Ritz, with Auguste Escoffier as the head chef. In its early days it was one of London's most fashionable hotels and drew some customers away from the Savoy Hotel, which Ritz and Escoffier had previously managed.
The hotel lost some of its prestige after Ritz retired, but continued to trade profitably until it was badly damaged by German bombing in 1940. The British government requisitioned the building in 1942. After the Second World War the shareholders of the hotel sold the lease of the site, and the surviving parts of the building were demolished in 1957–58. The site is now occupied by the 17-storey block of the New Zealand High Commission.
