HMS Rochfort was a 74-gun third rate ship of the line of the Royal Navy, launched on 6 August 1814 at Milford Haven.

She was designed by the French émigré Jean-Louis Barrallier, and was the only ship built to her draught.

[2] Lloyd's List reported in May 1817 that the Revenue cutter stork and Rochefort's tender "Cornelian" had recaptured the ship Catherina, of and from Hamburg for Lisbon, and the galiot Catherina, of Oldenborg from Antwerp for Havre, which a Tunesian schooner had captured on 27 May.

The British also captured the schooner and brought all three vessels into Dover.
