Sir Marmaduke Wyvill, 6th Baronet (1692–1754), of Constable Burton Hall, Yorkshire, was a British landowner and politician who sat in the House of Commons briefly from 1727 to 1728.
Wyvill was the son of Sir Marmaduke Wyvill, 5th Baronet MP of Constable Burton, Yorkshire, and his wife Henrietta Maria Yarburgh, daughter of Sir Thomas Yarburgh of Balne Hall and Snaith, Yorkshire.
At the 1722 British general election he was forbidden by his father to stand because Lord Sunderland disapproved.
Their friend the mayor, who was returning officer, allowed a large number of unqualified persons to vote for them.
In 1736, Wyvill's brother-in-law, Thomas Coke, 1st Earl of Leicester, the English postmaster general, appointed him postmaster general of Ireland, which disqualified him from sitting in the House of Commons.
