Admiral Sir George Augustus Elliot KCB (25 September 1813 – 13 December 1901) was a British Royal Navy flag officer and politician.

On 15 January 1838 he was made captain of the brig Columbine at the Cape and South Africa stations, under the direct command of his father, capturing six slavers in the two years he served in this position.

She was removed from active duty in 1853, and in January 1854 Elliot commissioned HMS James Watt, one of the first screw battleships, which he commanded in the Baltic campaigns of 1854 and 1855, despite the poor performance of the ship, and the dissatisfaction of Vice-Admiral Charles Napier.

In a dissenting report appended to the 1871 committee on designs, Elliot and Alfred Ryder, who believed that the ram was the primary weapon of naval combat, pressed for increased freeboard, the retention of sailing rig, and the concentration of armour.

In 1870 Elliot reached the rank of admiral, and in 1874 he was elected Conservative MP for Chatham; but he resigned his seat in 1875, on being appointed Commander-in-Chief, Portsmouth.
