The Haswell Islands are a group of rocky coastal islands lying off Mabus Point, Antarctica, and extending about 1.5 nautical miles (3 km) seaward. They were charted by the Australasian Antarctic Expedition under Douglas Mawson (1911–14), who applied the name "Rookery Islands" because of a large emperor penguin rookery on Haswell Island, the largest and seaward island in the group.
