La Pampilla refinery is an oil refinery in Peru, under the administration of Grupo Repsol del Perú S.A.C. It is located on Néstor Gambetta Avenue in Ventanilla, Callao, and has a capacity to refine 117,000 barrels of oil per day,^[1] which represents half of the country's refining production.

The construction of the refinery was put out to tender in 1964 and inaugurated in 1967,^[2] built by Petroperú. In 1996, the refinery became part of Repsol^[3] for around 180 million dollars, as part of the privatisation process carried out by former president Alberto Fujimori.

In 2014, the modernisation of the refinery began, estimated at US$740 million.^[4] It is expected that with the modernization the sulfur content will be reduced to 50 (ppm) by 2016 as well as the improvement of other fuels by 2018.^[5]

On January 15, 2022, and during the oil unloading process at the refinery, a crude oil spill occurred on the coast of the Ventanilla district, estimated at 6 thousand barrels of oil, aud thus affecting the flora and fauna of the Peruvian sea. It is considered the largest ecological disaster to occur on the Peruvian coast.^{[citation needed]}

The actions of the refinery and its owner, Repsol, have been harshly criticised for the cleaning and decontamination work carried out after the spill,^[6][7] reflecting the lack of a contingency plan for possible disasters.^[8]

The government's response was the stoppage of activities in terminal No. 2 of the refinery, ordered by the OSINERGMIN [es],^[9] and a fine amounting to 33.4 million dollars, as announced by the Minister of the Environment, Rubén Ramírez Mateo [es].^[10]
