Christchurch () is a town and civil parish in Dorset on the south coast of England. The town covers an area of 19.5 square miles and had a population of 48,368 in 2013. It adjoins Bournemouth to the west, with the New Forest to the east. Part of the historic county of Hampshire, Christchurch was a borough within the administrative county of Dorset from 1974 until 2019, when it became part of the new Bournemouth, Christchurch and Poole unitary authority.
Founded in the seventh century at the confluence of the rivers Avon and Stour which flow into Christchurch Harbour, the town was originally named Twynham but became known as Christchurch following the construction of the priory in 1094. The town developed into an important trading port, and was fortified in the 9th century.
