Port Sunlight is a model village, suburb and electoral ward in the Metropolitan Borough of Wirral, Merseyside, England. Historically part of Cheshire, it is located between Lower Bebington and New Ferry, on the Wirral Peninsula. Between 1894 and 1974 it formed part of Bebington urban district within the county of Cheshire. At the 2001 Census, its population was 1,450.
Port Sunlight was built by Lever Brothers to accommodate workers in its soap factory (now part of Unilever); work commenced in 1888. The name is derived from Lever Brothers' most popular brand of cleaning agent, Sunlight.
Port Sunlight contains 900 Grade II listed buildings, and was declared a Conservation Area in 1978. Port Sunlight has been informally suggested for World Heritage Site (WHS) status to protect it from development and to preserve the unique character for future generations; however, it is not yet on the current UK "tentative list" for future consideration as a WHS.
