Countess of Harcourt was a two-decker, teak merchant ship launched at Prince of Wales's Island in 1811, and sold in Great Britain in 1814.

Between the third and fourth of these, she undertook a voyage to China and Nova Scotia while under charter to the British East India Company (EIC).

On that voyage she carried the American Baptist missionaries Adoniram Judson and his wife, who were endeavouring to reach Penang, but ended up in Burma instead.

[6] The American privateer Sabine, of Baltimore, captured Countess of Harcourt, Davis, master, in June 1814 in the Channel while she was on her way to Isle of France (Mauritius) from London.

[5][11][b] Countess of Harcourt was carrying dry goods, brandy, rum, gin, etc., when she separated from the fleet in a gale.

The British also captured a quantity of cotton and tobacco which they loaded onto Countess of Harcourt with the aim of sending her to Bermuda.

The next day Scott found it necessary to abandon Countess of Harcourt and transfer everybody on board her to Doterel, leaving her drifting, but afloat.

[15] Eventually the news got to London where Lloyd's List reported that towards the end of February 1815 she lost her rudder and sails and her crew abandoned her.

Next morning a man from the signal post notified him that they had sighted a vessel answering the description of Countess of Harcourt.

[15] A race to retrieve her developed between Scott in the schooner-tender Anna Marie, which he had commandeered, and the brig-sloop HMS Harlequin.

[17] Captain John Brown protested the recapture of Sabine/Countess of Harcourt, arguing that the British seizure had been in violation of Spain's neutrality.

[14] He was apparently unsuccessful as prize money for Countess of Harcourt, the bark Maria Theresa, goods from the ship Carl Gustaff, and the schooner Cooler, was paid in April 1824.

Under the command of George Bunn, with surgeon Morgan Price, she sailed from Portsmouth on 19 April and arrived at Hobart Town on 27 July 1821.

On her second voyage transporting convicts, Captain Bunn and surgeon Robert Armstrong left Cork on 3 September 1822 and arrived at Port Jackson on 22 December.

Under the command of Captain Thomas Delafone (or Delaphon, or Delaphous[1]), she left The Downs on 25 June 1825, bound for China and Nova Scotia.

[4] The fourth voyage transporting convicts took place under the command of William Harrison, with surgeon Michael Goodsir.

[26] On her fifth voyage transporting convicts, Countess of Harcourt was under the command of William Harrison, with surgeon John Drummond.

[29] A more precise account has her wrecking on 18 December 1830 on the island of Corrente, Cape Passaro, a point on the southwest corner of Sicily (possibly near 36°41′13″N 15°08′54″E / 36.6869°N 15.1483°E / 36.6869; 15.1483), as she was transporting troops from Corfu to Malta.
