BAP Unión was a corvette of the Peruvian Navy, originally ordered by the government of the Confederate States of America during the American Civil War. Built in France it was bought by the Peruvian Navy and during its service participated in the Chincha Islands War and in the War of the Pacific in which it was scuttled following the Blockade of Callao to prevent it falling into Chilean hands. The current Peruvian training ship; BAP Unión, is named after this vessel.
