Ceres was an East Indiaman launched in 1787. She made three trips to China for the Honourable East India Company (HEIC). After the outbreak of war with France in 1793, the Admiralty, desirous of quickly building up the Royal Navy, purchased a number of commercial vessels, including nine East Indiamen, to meet the need for small two-decker fourth rates to serve as convoy escorts. The Admiralty purchased Ceres in 1795 and renamed her HMS Grampus. In 1797 the Admiralty converted her to a storeship. That year her crew participated in the Spithead and Nore mutinies. Grampus grounded in January 1799 and was abandoned.
