Morton Frederick Eden, 1st Baron Henley GCB PC FRS (8 July 1752 – 6 December 1830), was a British diplomat and peer.
Eden was the fifth son of Sir Robert Eden, 3rd Baronet and Mary Davison, youngest daughter of William Davison of Beamish, County Durham.
From 1776 to 1779, Eden was Minister to Bavaria, then to Copenhagen 1779–1782, Dresden 1783–1791, Berlin 1791–1793 and Vienna 1793–1794.
In 1799, Eden was created Baron Henley (Henly), of Chardstock, in the Peerage of Ireland,[3] in honour of his wife's family.
His wife was the co-heiress to her brother, Robert Henley, 2nd Earl of Northington, who died unmarried in 1786, and his earldom and subsidiary title of Baron Henley in the Peerage of Great Britain had become extinct.
