The Malvinas Basin (Spanish: Cuenca de Malvinas) is a major sedimentary basin in the Argentine Shelf offshore southern Patagonia. The basin borders to the west with the Río Chico-Dungeness High that separates it from the Magallanes Basin. The southern boundary is formed by the Scotia plate boundary. Contrary to the neighbouring North Falkland and Magallanes Basins, the Malvinas Basin is not known to have commercial hydrocarbon reserves.
