George Tobin (1768–1838) was an English Royal Navy officer and artist.
The second son of James Tobin of Nevis in the West Indies, and his wife Elizabeth Webbe, he was elder brother of John Tobin and James Webbe Tobin. He was born in England at Salisbury on 13 December 1768, and studied at King Edward VI School, Southampton. He entered the navy in 1780 on board the HMS Namur, in which he later went out to the West Indies, being present at the Battle of the Saintes during April 1782.
After the peace of 1783 Tobin was for some time in: HMS Bombay Castle, guardship at Plymouth; HMS Leander on the Halifax, Nova Scotia station, and in HMS Assistance. From 1788 to 1790 he made a voyage in the Sulivan, a ship of the East India Company. On his return he was for a few weeks on board HMS Tremendous during the Nootka Crisis, and on 22 November he was made a lieutenant.
During 1791–3 Tobin was in HMS Providence, captain William Bligh, on its voyage to Tahiti and the West Indies. He kept an illustrated journal, covering in particular Tahiti and Tasmania. It is now in the State Library of New South Wales.
On his return to England Tobin learned that by his absence he had avoided being appointed third lieutenant of HMS Agamemnon, captain Horatio Nelson: Nelson through his wife was connected with Tobin's family. He was instead appointed second lieutenant of the frigate HMS Thetis, captain Alexander Cochrane, which he considered a better outcome. Nelson, however, regretted it, writing of Tobin, on 12 July 1797, "The time is past for doing anything for him. Had he been with me, he would long since have been a captain, and I should have liked it, as being most exceedingly pleased with him."
