Admiral Sir Archibald Gordon Henry Wilson Moore, KCB, CVO (2 February 1862 – 2 April 1934) was a Royal Navy officer who served as Third Sea Lord from 1912 to 1914.

Moore joined the Royal Navy in 1875 and served in the Anglo-Egyptian War of 1882.

[2] In early 1903 he took part in the special mission (headed by Lord Downe) deputized by the King to travel to Iran to present the Shah with the insignia of the Order of the Garter.

[1] As Vice Admiral Sir David Beatty's second-in-command at the Battle of Dogger Bank, Moore led the sinking of SMS Blücher in January 1915.

[5] Military historian Chuck Steele wrote in 2022 that Moore's transfer actually resulted from his complaints to Winston Churchill, then First Lord of the Admiralty, about Beatty's signaling failures; even Beatty privately expressed his belief that Moore was being scapegoated.
