Cato was a merchant vessel launched at Kingston upon Hull in 1807. She was a West Indiaman, a transport ship, and traded across the Atlantic between England and North America. She foundered in November 1841.
Cato first appeared in Lloyd's Register (LR) in 1808.
Captain John Hossack acquired a letter of marque on 6 December 1808.
A gale on 13 January 1828 drove the transport ship Cato, and several other vessels, ashore in Mountbatten Bay. The initial report was that her rudder had been unshipped and that her keel was much damaged, but that it was expected that she would be refloated.
Lloyd's List reported on 22 December 1835 that Cato had arrived at Liverpool from Quebec in a much damaged state.
On 11 November 1844 her crew, who were rescued, abandoned Cato west south west of the Isles of Scilly. She had become waterlogged as she sailed from Quebec City, to Plymouth. Her entry in LR bears the annotation "Abandoned".
