HMS Audacious was the lead ship of the Audacious-class ironclads built for the Royal Navy in the late 1860s. They were designed as second-class ironclads suitable for use on foreign stations and the ship spent the bulk of her career on the China Station. She was decommissioned in 1894 and hulked in 1902 for use as a training ship. The ship was towed to Scapa Flow after the beginning of the First World War to be used as a receiving ship and then to Rosyth after the war ended. Audacious was sold for scrap in 1929.
