HMS Hibernia was a 110-gun first rate ship of the line of the Royal Navy. She was launched at Plymouth dockyard on 17 November 1804, and was the only ship built to her draught, designed by Sir John Henslow.
She was flagship of the British Mediterranean Fleet from 1816 until 1855, when she became the flagship for the Royal Navy's base at Malta and stationed in Grand Harbour. She remained in this role until she was sold in 1902.
The ten-day court-martial of the surviving officers and crewmen of the battleship HMS Victoria for the loss of their ship in a 22 June 1893 collision with the battleship HMS Camperdown was held on Hibernia's deck. The proceedings began on 17 July 1893.
Between 1807 and 1808, HMS Hibernia, under the command of Sir William Sidney Smith, lead the British scout of the Portuguese Royal Family during the Transfer of the Portuguese Court to Brazil.
Hibernia's figurehead is in the Maritime Museum, Vittoriosa, Malta.
HMS Hibernia's scrapage for timber that was used predominantly to fire bakeries in Malta, led to a substantial outbreak of lead poisoning on the island.
