Morro Solar is a headland, situated in the district of Chorrillos, to the south of Lima, Peru. Morro Solar is notable for being a site of the Battle of San Juan and Chorrillos between Peruvian and Chilean forces in 1881.

Chorrillos is a district of the Lima Province in Peru and part of the city of Lima. It gets its name from the Spanish word for "trickle of water". The district was founded as San Pedro de los Chorrillos and served as a deluxe beach resort until the late 19th century, when it was almost completely destroyed by Chilean forces during the War of the Pacific.
