HMS Ocean (1862)
 HMS Ocean was the last of the Royal Navy's four Prince Consort-class ironclads to be completed in the mid-1860s. She was originally laid down as a 91-gun second-rate ship of the line and was converted during construction to an armoured frigate. The ship spent the bulk of her career on the China Station and served as flagship there for a time. Upon her return to Great Britain in 1872 her hull was found to be partly rotten and she was placed in reserve until she was sold for scrap in 1882.
