Chelsea is an area of West London, Great Britain, bounded to the south by the River Thames, where its frontage runs from Chelsea Bridge along the Chelsea Embankment, Cheyne Walk, Lots Road and Chelsea Harbour. Its eastern boundary was once defined by the River Westbourne, which is now in a pipe above Sloane Square tube station. The modern eastern boundary is Chelsea Bridge Road and the lower half of Sloane Street, including Sloane Square, along with parts of Belgravia . To the north and northwest, the area fades into Knightsbridge and South Kensington, but it is safe to say that the area north of King's Road as far northwest as Fulham Road is part of Chelsea.
The district is part of the Royal Borough of Kensington and Chelsea. From 1900, and until the creation of Greater London in 1965, it formed the Metropolitan Borough of Chelsea in the County of London. Chelsea Football Club has its grounds at Stamford Bridge, in neighbouring Fulham.
