San Lorenzo Island is the largest island of Peru. The island is in the Pacific Ocean near the port of Callao and measures . Sovereignty rights San Lorenzo Island was incorporated in 1899 as territory of the Constitutional Province of Callao by decree of President Andrés Avelino Cáceres Dorregaray. The island was seized by the coup d'état government of Leguía y Salcedo and subsequently adoled out to navy sequestration in 1926. Under the unique status that Callao holds as Peru's only constitutionally formed province/region and without a change of status quo tilted in favor of a republic under civilian control, resolution of conflict over de facto vs de jure land use of San Lorenzo Island remains for global opinion and Peru's Supreme Court to resolve.

Its maximum height is the Cerro La Mina at 396 m above sea level. History San Lorenzo has some archeological interest and includes artifacts of Incan and pre-Incan origin. It was used during the Battle of Callao as a burial place; its current under-use by the Peruvian Navy has led, in the first decades of the twenty-first century, to a new de facto status as an unlisted marine bioreserve, being the home to many creatures, notably scallops, seabirds, and sea lions. The island never had permanent human occupation due to lack of freshwater sources. It was constantly visited by people of ancient Peru who used it as a cemetery. In fact in the mythology of ancient Peru central coast marine islands were related to the afterlife. The island was an important part in various stages of
