The South east Dorset conurbation (also known as the South Dorset conurbation, Poole-Bournemouth urban area and Bournemouth urban area) is a multi-centred conurbation on the south coast of Dorset in England. The area is rapidly becoming an amalgamation with the area of South West Hampshire immediately on the fringe of the newly formed New Forest National Park. The main population centres are Bournemouth, Poole and Christchurch; however, the urbanised area spreads as far east as Barton on Sea in Hampshire. There are a number of satellite towns peripheral to these main urban centres. In clockwise rotation these include: Wareham, Upton, Wimborne, Ferndown, Verwood and Ringwood (Hampshire). The urban area is generally surrounded by a green belt.
