HMS Dublin was a 74-gun third rate ship of the line of the Royal Navy, launched on 13 February 1812 at Rotherhithe.
In 1826 she was reduced to a 40-gun ship. She became the flagship of Commander-in-Chief of the Pacific fleet Admiral Sir Graham Hamond, 2nd Baronet from 1835 to 1838, and Rear Admiral Richard Darton Thomas (1777–1857), from 1841 to 1845.
Dublin was sold out of the Navy in 1885.
