Huáscar is an ironclad turret ship owned by the Chilean Navy built in 1865 for the Peruvian government. It is named after the 16th-century Inca emperor, Huáscar. She was the flagship of the Peruvian Navy and participated in the Battle of Pacocha and the War of the Pacific of 1879–1883. At the Battle of Angamos, Huáscar, captained by renowned Peruvian naval officer Miguel Grau Seminario, was captured by the Chilean fleet and commissioned into the Chilean Navy.

The Battle of Angamos was a naval encounter of the War of the Pacific fought between the navies of Chile and Perú at Punta Angamos, on 8 October 1879. The battle was the culminating point of a naval campaign that lasted about five months in which the Chilean Navy had the sole mission of eliminating its Peruvian counterpart. In the struggle, two armored frigates, led by Commodore Galvarino Riveros Cárdenas and Navy Captain Juan José Latorre battered and later captured the Peruvian monitor Huáscar, under Rear Admiral Miguel Grau Seminario.
