Peru v Chile (also called the Chilean–Peruvian maritime dispute) is a public international law case concerning a territorial dispute between the South American republics of Peru and Chile over the sovereignty of an area at sea in the Pacific Ocean approximately 37,900 square kilometres (14,600 sq mi) in size. Peru contended that its maritime boundary delimitation with Chile was not fixed, but Chile claimed that it holds no outstanding border issues with Peru. On January 16, 2008, Peru brought forth the case to the International Court of Justice at The Hague, the Netherlands, which accepted the case and formally filed it as the Case concerning maritime delimitation between the Republic of Peru and the Republic of Chile - Perú v. Chile.
