Hope Bay (Spanish: Bahía Esperanza) (63°23′S 56°59′W / 63.383°S 56.983°W / -63.383; -56.983 (Hope Bay)) is a bay 3 nautical miles (5.6 km; 3.5 mi) long and 2 nautical miles (3.7 km; 2.3 mi) wide, indenting the tip of the Antarctic Peninsula and opening on Antarctic Sound.

Hope Bay is in Graham Land on the north coast of the Trinity Peninsula, which forms the tip of the Antarctic Peninsula. Hope bay is south of Mount Bransfield and southwest of the Mott Snowfield. It opens onto the Antarctic Sound to the west, and faces Joinville Island. It defines the northeast end of the Tabarin Peninsula. Features and nearby features include, clockwise from the east, Mount Flora, Mount Carroll, Depot Glacier, Mount Cardinal, Mount Taylor, Whitten Peak, Twin Peaks, Arena Glacier and Andersson Nunatak.

The US Defense Mapping Agency's Sailing Directions for Antarctica (1976) describes Hope Bay as follows:

Hope Bay is about 1 2/3 miles wide between Sheppard and Stone Points, Its northwestern and southeastern entrance points, respectively, and indents the coast to a distance of 2 1/2 miles in a southwest direction. The northwestern entrance is a steep wall of ice which, on entering the bay, is backed by steep, sharp-ridged mountains, which trend southwestward forming the walls of a valley. A nunatak with a cliff about 300 feet high, located 2 1/4 miles southwestward of Sheppard Point, is conspicuous. On the opposite side of the bay several lofty pyramidical nunataks are conspicuous on the high, rocky wall. From the southeastern promontory the slopes descend to a low, hilly foreland. At the head of the bay there is a large valley glacier and lateral moraine which terminates at the water's edge in a high vertical cliff. This glacier is fed by the highland ice sheet which extends for some distance southward.

Whitten Peak, at the head of the bay, rises to an elevation of 1,465 feet, and is backed by Mount Taylor, 3,274 feet high, flat-topped and icecapped. Mount Flora, 1,708 feet high, stands at the head of the bay, on the eastern side.

Hope Bay was discovered on January 15, 1902 by the Swedish Antarctic Expedition (SwedAE) under Otto Nordenskiöld, who named it in commemoration of the winter spent there by J. Gunnar Andersson, S.A. Duse, and Toralf Grunden of his expedition, after his ship (the Antarctic) was crushed by the ice and lost. They were eventually rescued by Argentine corvette Uruguay.

The ruins of a stone hut built in January 1903 by members of the Swedish expedition can still be seen; it has been designated a Historic Site or Monument (HSM 39), following a proposal by Argentina and the United Kingdom to the Antarctic Treaty Consultative Meeting.

Hope Bay was also the scene of the Hope Bay incident when the only shots ever fired in anger in Antarctica took place, in 1952. An Argentine shore party fired a machine gun over the heads of a British Antarctic Survey team unloading supplies from the John Biscoe. The Argentines later extended a diplomatic apology, saying that there had been a misunderstanding and that the Argentine military commander on the ground had exceeded his authority. However, the Argentine party was given a hero's welcome upon its return to Argentina.^{[citation needed]}
