Admiral of the Fleet Sir George Francis Seymour, GCB, GCH, PC (17 September 1787 – 20 January 1870) was a Royal Navy officer.

[2] He was present when the Batavian Republic surrendered Suriname to British forces in August 1799 during the French Revolutionary Wars and, having been promoted to midshipman, transferred to the fifth-rate HMS Acasta early in 1800.

[2] In HMS Donegal he took part in the pursuit of the French Fleet, under the command of Admiral Pierre-Charles Villeneuve, to the West Indies and back in Summer 1805 during the Napoleonic Wars before seeing action at the capture of the Spanish 100-gun Rayo in October 1805.

[3] Promoted to commander on 23 January 1806, Seymour became commanding officer of the third-rate HMS Northumberland, flagship of the West Indies Squadron, in January 1806 and fought under Admiral Sir John Duckworth at the Battle of San Domingo where he was wounded off the southern coast of the French-occupied Spanish colony San Domingo in the Caribbean Sea in February 1806.

[5] He became Serjeant-at-Arms to the House of Lords in 1818 and was given a short leave of absence to undertake a tour as commanding officer of the fifth-rate HMS Briton on "particular service" in 1827.

The expulsion of the consul became known as the "Pritchard Affair", a business which Seymour handled tactfully avoiding a confrontation with the French Government who had already denounced Thouars' actions.

[10] Tensions with United States were high as a result of the Oregon boundary dispute and Seymour avoided inflaming this situation in discussions over fisheries.

[9] Promoted to vice-admiral on 27 March 1850,[11] Seymour became Commander-in-Chief North America and West Indies Station, with his flag in the third-rate HMS Cumberland, in January 1851.
