Matthews Island is the largest of the Robertson Islands in the South Orkney Islands off Antarctica. It lies immediately south-east of Coronation Island, from which it is separated by a narrow channel known as the Divide. Matthews Island was mapped as part of Coronation Island until January 1957 when a Falkland Islands Dependencies Survey (FIDS) party established its insularity. It was named by the UK Antarctic Place-Names Committee in 1959 for Drummond H. Matthews, a FIDS geologist at Signy Island in 1956.
