Several vessels have borne the name Kitty, a diminutive for the name "Catherine", and a name in its own right:
- Kitty, of 12653⁄94 tons (bm), was a vessel that HMS Bellona captured from the French c.1778. The High Court of Admiralty condemned her on 14 April 1779 and Crosbie and Granwood, Liverpool merchants, purchased her that year. She stranded on the coast of Ireland and was sold there.
- Kitty (1784 ship), of 333 tons (bm), was launched at Liverpool in 1784. Between 1788 and 1805 she made nine voyages as a slaver. She then became a privateer, cruising off the River Plate. The French privateer Caffard captured her in 1806.[3]
- Kitty (1787 ship) was a merchantman built at Sunderland in 1787. In 1790 she carried slaves from the Gold Coast to Jamaica. Then in 1791 she transported convicts and goods from England to Australia. She was last listed in 1805.
- Kitty (1800 ship) was a West Indiaman, then served the Royal Navy from 17 May 1804 to 17 January 1805, became a privateer with a notable single-ship action to her credit, a merchantman trading with Russia, a whaler, and a merchantman again. She was last listed in 1852.
- Kitty (1810 ship) was a French vessel taken in prize c. 1810. She became a West Indiaman and then, following a change of ownership, a privateer. She was one of only two British privateers to target slave traders. She captured three off Sierra Leone before one of her targets captured her in 1814, killing her master, enslaving some of her crew, and setting fire to her.
- Kitty (1850 ship) was launched at Sunderland. The Hudson's Bay Company chartered her in 1859 and she wrecked in Hudson's Strait later that year.[4]
