Cape Gerlache is a rocky headland on the Antarctic Peninsula. It is situated on the western side of Graham Land, forming part of the entrance to the Gerlache Strait, which separates the peninsula from the Palmer Archipelago.
The cape was charted by the Belgian Antarctic Expedition of 1897–99, which was led by Adrien de Gerlache. In recognition of the expedition leader, the feature was named “Cape Gerlache” by the expedition’s cartographers.
The location lies within the area governed by the Antarctic Treaty System, and like other Antarctic geographic features, it is recorded in the Scientific Committee on Antarctic Research (SCAR) Composite Gazetteer of Antarctica.
No permanent human settlement exists at Cape Gerlache; the surrounding region is covered primarily by ice, snow, and occasional exposed rock outcrops, and it is visited only infrequently by scientific and logistic operations.
