A number of sailing ships have been named Marquis of Wellington:
- Marquis of Wellington, a 653-ton merchantman launched in 1801 at Calcutta as Betsey. She made two voyages for the British East India Company, one under each name. She was wrecked in 1818.
- Marquis of Wellington (1812 EIC ship), of 961 or 109030⁄94 tons (bm), was laid down on 30 April 1811 as Lord Nelson,[1] but was launched on 22 October 1812 by Frances Barnard, Son & Roberts, Deptford, for Henry Bonham. Her first captain, John Wood, received a letter of marque on 20 January 1813. That letter gave her complement as 120 men and her armament as thirty-two 18-pounder guns. Between 1813 and 1830 she made nine voyages for the EIC.[2] On 11 September 1832 her owners sold her to Dom Pedro, Pretender to the Portuguese throne, who converted her into a frigate. Taken back by her owners and reverted to a merchantman after the failure of his campaign. In 1855 she was sold for breaking up.
