HMS Ardent (1841)
 HMS Ardent was a wooden Alecto-class paddle sloop and the fourth ship of the Royal Navy to use the name. She was launched on 12 February 1841 at Chatham and spent much of her career on the West Coast of Africa engaged in anti-slavery operations. One of the ship's company Gunner John Robarts was awarded the Victoria Cross for the destruction of Russian food stores in the Crimean War. She was scrapped in 1865.
