HMS Royal Oak was a Prince Consort-class armoured frigate built for the Royal Navy in the 1860s. The lead ship of her class, she is sometimes described as a half-sister to the other three ships because of her different engine and boiler arrangements. Like her sisters, she was converted into an ironclad from a wooden ship of the line that was still under construction.
