Chelsea Harbour is a contemporary mixed-use development in West London, situated in its Sands End area, along Chelsea Creek, the historic southeastern boundary of the London Borough of Hammersmith and Fulham with the southwestern boundary of the Royal Borough of Kensington and Chelsea, and opposite the site of the old Lots Road Power Station in Chelsea. The development consists of luxury apartments, the Chelsea Harbour Marina and the Chelsea Harbour Design Centre and a hotel, 'the Chelsea Harbour Hotel'.

Sands End is an area of the ancient parish of Fulham, formerly in the County of Middlesex, which is now the southernmost part of the London Borough of Hammersmith and Fulham, England. In a deep loop of the River Thames, between the tidal Chelsea Creek and the old Peterborough estate, west of Wandsworth Bridge, its northern edge is New King's Road. While wharves, industrial acres and workers' cottages gave way to intensive re-development such as Chelsea Harbour and Imperial Wharf in the last quarter of the 20th-century, it still contains some 300-year-old cottages and 19th century streets.
