Brown Peninsula (78°6′S 165°25′E) is a nearly ice-free peninsula, 10 nautical miles (19 km) long and 4 nautical miles (7 km) wide, which rises above the Ross Ice Shelf northward of Mount Discovery, to which it is connected by a low isthmus. It was discovered by the British National Antarctic Expedition, 1901–04, which named it "Brown Island" because of its color and its island-like character. Since it is a peninsula, the name has been altered accordingly.
