Longparish is a village and civil parish in Hampshire, England. It is composed of 4 hamlets that over time have expanded and joined up to become one village. Longparish is situated on the northwest bank of the River Test. In 2011 the population (including Firgo and Forton) was 716.
The name Longparish was first used in the mid-16th-century and is derived from a nickname for the "long parish" of Middleton — consisting of the settlements of Middleton, East Aston, West Aston and Forton — which stretched some 4 miles along the River Test. The parish of Middleton was first recorded as "Middletune" in the Domesday Survey of 1086.
