William Hayward was an architect active, particularly in Shrewsbury and Oxford, England, in the mid- to late-18th century. He was born in 1740, the son of John Hayward of Lincoln, England (died 1778) and is most noted perhaps for his work on bridges. Hayward died in 1782 and despite his wish to be buried under the arch of one of his constructions, was buried in Henley Parish Church.
