Sir William Willys, 6th Baronet (c. 1685–1732) was a British politician who sat in the House of Commons from 1727 to 1732.
Willys was the second son of William Willys of Austin Friars, and his wife Catherine Gore, daughter of Robert Gore merchant of Chelsea and widow of George Evelyn.
His father was the fourth son of Sir Thomas Willys, 1st Baronet and was a London merchant trading with Hamburg.
[2] Willys was returned as Member of Parliament for Newport (Isle of Wight) at a by-election on 31 January 1727.
At the 1727 general election he stood instead at Great Bedwyn, probably with the support of his brother-in-law Francis Stonehouse, and topped the poll.
