The 2022 Callao oil spill is a crude oil spill that occurred on 15 January 2022, on the coast of the Ventanilla district in the constitutional province of Callao, Peru, after abnormal waves caused by the volcanic eruption in Tonga and alleged negligence on the side of company Repsol.

The spill began in the early morning of 15 January 2022 during the process of unloading crude oil at the La Pampilla refinery of the Spanish company Repsol in Callao.

Initially, Repsol indicated that only 7 gallons of crude oil had been spilled,[2] but in the morning it was found that the magnitude of the disaster was vastly greater, calculating 6,000 barrels dumped into the sea.

According to the Agency for Environmental Assessment and Enforcement (OEFA), the oil spill affects some 1,187 km2 (458 sq mi) of sea and 1,740 km2 (670 sq mi) of beach-coastal strip, about 17 beaches have been affected from the La Pampilla refinery to Peralvillo beach in Chancay and more than 500 ha (1,200 acres) of the protected natural areas of the National Reserve System of Guaneras Islands, Islets and Points and the Reserved Zone of Ancón.
