Blanco Encalada was an armored frigate built by Earle's Shipbuilding Co. in England for the Chilean Navy in 1875. She was nicknamed El Blanco. She participated actively in the War of the Pacific, her most important action being the capture of the Peruvian monitor Huáscar during the Battle of Angamos. Blanco Encalada formed part of the congressional forces that brought down President José Manuel Balmaceda in the Chilean Civil War of 1891. She was sunk during that conflict on 23 April 1891, becoming the first warship to be sunk by a self-propelled torpedo.
