HMS Calcutta was an East Indiaman converted to a Royal Navy 56-gun fourth rate. This ship of the line served for a time as an armed transport. She also transported convicts to Australia in a voyage that became a circumnavigation of the world. The French 74-gun Magnanime captured Calcutta in 1805. In 1809, after she ran aground during the Battle of the Basque Roads and her crew had abandoned her, a British boarding party burned her.
