is an area of South West London, bounded to the south by the River Thames. Its river 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 Underground station. The modern eastern boundary is Chelsea Bridge Road and the lower half of Sloane Street, including Sloane Square. To the north and northwest, the area fades into Knightsbridge and Brompton, but it is considered that the area north of King's Road as far northwest as Fulham Road is part of Chelsea.
