HMS Duchess was a 90-gun second rate ship of the line of the Royal Navy, built by John Shish at Deptford Dockyard, and launched in 1679. She was renamed HMS Princess Anne in 1701, HMS Windsor Castle in 1702, and HMS Blenheim in 1706. In 1709 Blenheim was rebuilt at Woolwich Dockyard, remaining a 90-gun second rate. She continued to serve until 1763, when she was broken up.
