Morton Frederick Eden, 1st Baron Henley (8 July 1752 â 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. His three eldest brothers were Sir John Eden, 4th Baronet, Sir Robert Eden, 1st Baronet, of Maryland, and William Eden, 1st Baron Auckland.
He was educated at Eton and Christ Church, Oxford.
From 1776 to 1779, Eden was Minister to Bavaria, then to Copenhagen 1779âÂÂ1782, Dresden 1783âÂÂ1791, Berlin 1791âÂÂ1793 and Vienna 1793âÂÂ1794. From 1794 to 1795, he was Ambassador to Spain, and returned as Minister to Vienna in 1794âÂÂ1799. He then retired with a pension of ã2000.
Eden was knighted in 1791 and admitted to the Privy Council in 1794. In 1799, Eden was created Baron Henley (Henly), of Chardstock, in the Peerage of Ireland, in honour of his wife's family.

Lord Henley died in 1830 and was succeeded by his eldest surviving son, Robert, who adopted the surname Henley.
