Belisarius was launched in Massachusetts in 1781. The British Royal Navy captured later that year and took her into service as HMS Bellisarius. She captured several American privateers, including one in a single ship action, before the Navy sold her in 1784. Her new owners sailed her as a merchantman between London and British Honduras. In 1787 she carried emigrants to Sierra Leone for the Committee for the Relief of the Black Poor, before returning to trading with Honduras. She was wrecked in September 1787.
