In England, a civil parish (CP) is a territorial designation which is the lowest tier of local government below districts and counties, or their combined form, the unitary authority. It is an administrative parish, in contrast to an ecclesiastical parish. 

A civil parish can range in size from a large town with a population of about 80,000 to a single village with fewer than a hundred inhabitants. In a limited number of cases a parish might include a whole city where city status has been granted by the Monarch. Reflecting this diverse nature, a civil parish may be known as a town, village, neighbourhood or community by resolution of its parish council. Approximately 35% of the English population live in a civil parish. As of 31 December 2015 there were 10,449 parishes in England. 

On 1 April 2014, Queen's Park became the first civil parish in Greater London. Before 2008 their creation was not permitted within a London borough. 

The division of land into ancient parishes was linked to the manorial system: parishes and manors often covered the same area and had the same boundaries. The manor was the principal unit of local administration and justice in the early rural economy. Later the church replaced the manor court as the rural administrative centre, and levied a local tax on produce known as a tithe. In the medieval period, responsibilities such as relief of the poor passed increasingly from the Lord of the Manor to the parish's rector, who in practice would delegate tasks among his vestry or the (often well-endowed) monasteries. After the dissolution of the monasteries, the power to levy a rate to fund relief of the poor was conferred on the parish authorities by the Act for the Relief of the Poor 1601. Both before and after this optional social change, local (vestry-administered) charities are well-documented.
