Bournemouth is a large coastal resort town in the county of Dorset, England. According to the 2001 Census the town has a population of 163,444, making it the largest settlement in Dorset. It is also the largest settlement between Southampton and Plymouth. With Poole and Christchurch, Bournemouth forms the South East Dorset conurbation, which has a total population of approximately 400,000.

Founded in 1810 by Lewis Tregonwell, Bournemouth's growth accelerated with the arrival of the railway, becoming a recognised town in 1870. Originally part of Hampshire, it joined Dorset with the reorganisation of local government in 1974. Since 1997 the town has been administered by a unitary authority, meaning that it has autonomy from Dorset County Council. The local authority is Bournemouth Borough Council.
