Admiral Sir Peter Halkett, 6th Baronet (c. 1765 – 7 October 1839) was a senior Royal Navy officer of the early nineteenth century who is best known for his service in the French Revolutionary Wars.

During the campaign, Halkett served in gunboats assisting the Dutch garrison during the Siege of Williamstadt and impressed the Duke with his activity, being rewarded with a promotion to post captain and an expensive medal from the Prince of Orange.

[1] On his return to Britain, Halkett was given command of the frigate HMS Circe in the North Sea, and in 1797 his ship was one of the few not to suffer from the effects of the Nore Mutiny that brought the fleet to a standstill.

At the subsequent court martial Halkett was cleared of any blame in the loss of his ship, the pilot being broke and rendered incapable of ever serving his Majesty,[2] and he was given command of a new frigate, also named HMS Apollo.

[1] In Apollo, Halkett sailed for the West Indies and remained there for two years, capturing a number of French and Spanish vessels, including privateers.
