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.

Turret ships were a 19th-century type of warship, the earliest to have their guns mounted in a revolving gun turret, instead of a broadside arrangement.
