Belgrano II Base (Spanish: Base Belgrano II) is a permanent, all year-round Argentine Antarctic base and scientific research station named after General Manuel Belgrano, one of the Libertadores and the creator of the Argentine Flag. It is located on Bertrab Nunatak on the Confín Coast, Coats Land. As of 2022 it is Argentina's southernmost permanent base, the world's third furthest south permanent base, and the world's southernmost base built on solid rock, which makes it particularly suited for geological research. As of 2022 Belgrano II is one of 13 research stations in Antarctica operated by Argentina.
