The May Fair Hotel is a luxury hotel on Stratton Street in Mayfair, London, near the site of Devonshire House in Piccadilly. It opened in 1927 with King George V and Queen Mary in attendance. The hotel is now owned by Edwardian Hotels, and Inderneel Singh, son of the chairman and CEO Jasminder Singh, is the managing director. The 404-room hotel completed a $150 million renovation in November 2006. The building also houses the May Fair Theatre, which opened in 1963. In 2005, a blue plaque was unveiled to commemorate dance band leader Ambrose, who performed regularly at the hotel. Eric Parkin was a cocktail pianist there in the 1940s. In June 2019, the hotel joined the Radisson Collection brand.
