William Henry Wills, 1st Baron Winterstoke Bt (September 1 1830 – January 29 1911), was the first chairman of Imperial Tobacco. He was from the wealthy Bristol tobacco importing Wills family.
In 1904 Wills gave the people of Bristol the gift of the Bristol City Museum and Art Gallery. He was made a baronet in 1893 and was subsequently raised to the peerage in 1906.
When he died in 1911 Wills' estate was worth UK £2,548,209. Lord Winterstoke died without heirs, so the title Lord Winterstoke became extinct upon his death.
William was the brother of Henry Overton Wills III, first chancellor of the University of Bristol.
