HMS Northumberland was a 70-gun third-rate ship of the line of the Royal Navy, built by Francis Bayley of Bristol in 1677/79. She partook in the last great battle of the War of English Succession and the first battle of the War of Spanish Succession. She was lost in the Great Storm of November 1703. She was named in honour of Charles II illegitimate son, George Fitzroy, his son with Barbara Palmer (Duchess of Cleveland). George Fitzroy was made the Duke of Northumberland in 1678. This was the first vessel to bear the name Northumberland in the English and Royal Navy.
