Six ships of the Royal Navy have borne the name HMS Pluto, after Pluto, a God of Roman mythology:

• HMS Pluto (1745) was an 8-gun fire ship purchased from civilian service in 1745 when she had been named Roman Emperor. She was sold in 1747.
• HMS Pluto (1756) was an 8-gun fire ship purchased from civilian service in 1756 when she had been named New Concord. She was sold in 1762.
• HMS Pluto was previously HMS Tamar, a 16-gun sloop. She was renamed HMS Pluto when she was converted into a fire ship in 1777. The French privateer Duc de Chartres captured her on 30 November 1780. Pluto's subsequent fate is unknown.
• HMS Pluto (1782) was a 14-gun fire ship of the Royal Navy launched in 1782. Pluto was converted to a sloop in 1793. She spent the period of the French Revolutionary Wars on the Newfoundland station where she captured a French naval vessel. During the Napoleonic Wars Pluto was stationed in the Channel. There she detained numerous merchant vessels trading with France or elsewhere. Pluto was laid up in 1809 and sold in 1817 into mercantile service. The mercantile Pluto ran aground near Margate on 31 August 1817 and filled with water.

• INS Pluto was a steam frigate of the Indian Navy that the Bombay Dockyard launched for the British East India Company on 12 September 1843.^[1]
