Admiral of the Fleet Sir Charles Edward Madden, 1st Baronet, GCB, OM, GCVO, KCMG, (5 September 1862 – 5 June 1935) was a Royal Navy officer who served during the First World War as Chief of the Staff to Sir John Jellicoe in the Grand Fleet from 1914 to 1916 and as Second-in-Command of the fleet under Sir David Beatty from 1916 to 1919. He was Commander-in-Chief of the Atlantic Fleet after the war and served as First Sea Lord in the late 1920s. In that role, in order to avoid an arms race, he accepted parity with the United States in the form of 50 cruisers defending his position on the basis that he only actually had 48 cruisers anyway.
