Maher Island is a small horseshoe-shaped island lying 10 km (6.2 mi) north of the north-western end of Siple Island, off the coast of Marie Byrd Land, Antarctica. It is one of the three pieces of land closest to the Oceanic Pole of Inaccessibility, also known as 'Point Nemo', the other two being Ducie Island, one of the Pitcairn Islands, and Motu Nui near Easter Island. It has numerous areas of exposed rock and is mostly ice-free in summer.
