Marylebone is an affluent inner-city area of central London, England, located within the City of Westminster. It is sometimes written as St. Marylebone (or, archaically, Mary-le-Bone).
Marylebone is roughly bounded by Oxford Street to the south, Marylebone Road to the north, Edgware Road to the west and Great Portland Street to the east. A broader definition designates the historic area as Marylebone Village and encompasses neighbouring Regent’s Park, Baker Street and the area immediately north of Marylebone Road, containing Marylebone Station, the original site of the Marylebone Cricket Club at Dorset Square, and the neighbourhood known as Lisson Grove as far as the border with St John’s Wood. The area east of Great Portland Street up to Cleveland Street, known as Fitzrovia since the 1940s, is considered historically to be East Marylebone.
