William Owen was an English architect who practised in Warrington, which was at that time in Lancashire, England. His works were confined to Northwest England. Owen is best known for his collaboration with William Lever in the creation of the soap-making factory and associated model village at Port Sunlight in the Wirral Peninsula. Here he designed the factory, many of the workers' houses, public buildings and the church. Later Owen was joined by his son, Segar, as a partner. On his own, or in partnership, Owen designed houses, churches, banks, public houses, an infirmary, a school, and a concert hall.

Port Sunlight is a model village in the Metropolitan Borough of Wirral, Merseyside, England. It is located between Lower Bebington and New Ferry, on the Wirral Peninsula. Port Sunlight was built by Lever Brothers to accommodate workers in its soap factory ; work commenced in 1888. The name is derived from Lever Brothers' most popular brand of cleaning agent, Sunlight.
