List of ships named Lord Cathcart

Three vessels launched in 1807–1808 were named Lord Cathcart for William Cathcart, 1st Earl Cathcart. All three were ill-fated, being wrecked between 1820 and 1822. Before they wrecked, all three made a voyage to India c.1817. The British East India Company (EIC) in 1813 lost its monopoly on the Britain–India trade and thereafter private vessels sailed under an EIC license for their voyage.
