Andersen Island is an island 40NaN0 west of Thorgaut Island, and 20NaN0 east of Child Rocks, in the Robinson Group, Antarctica. It was mapped by the British Australian New Zealand Antarctic Research Expedition under Douglas Mawson in February 1931. The island was also charted from the whaler Thorgaut about the same time. It was named after Captain Lars Andersen of the whaler Falk who had assisted the Discovery with coal.
A 111 ha site encompassing breeding colonies of some 13,000 pairs of Adélie penguins on Andersen Island and an unnamed island 1 km to the south-west has been identified as an Important Bird Area by BirdLife International.[1]
