George Legge, 1st Baron Dartmouth PC (c. 1647 – 25 October 1691) was a Royal Navy officer and politician who was appointed Admiral of the Fleet by James II of England in September 1688.

A close friend of Prince Rupert of the Rhine, Colonel Legge served in the Royalist army during the Wars of the Three Kingdoms and was arrested several times during The Protectorate for conspiring to restore Charles II.

[5] Educated at Westminster School and King's College, Cambridge, Legge began his naval career during the Second Anglo-Dutch War, when he served as a volunteer under his cousin Admiral Sir Edward Spragge in the 1666 Four Days' Battle.

[4] Despite this inauspicious beginning, he was appointed Groom of the Chamber to the future James II of England in 1669, then given command of HMS Fairfax in January 1672.

His last naval appointment was to the command of a fleet in the channel which unsuccessfully attempted to intercept the invasion force led by William III of Orange that landed in 1688 at the beginning of the Glorious Revolution.
