Abemama (Apamama), or for a short time after appearing on European maps, Roger Simpson Island, is an atoll, one of the Gilberts group in Kiribati, and is located 152 kilometres (94 miles) southeast of Tarawa and just north of the Equator. Abemama has an area of 27.37 square kilometres (10.57 square miles) and a population of 3,213 as of 2010. The islets surround a deep lagoon. The eastern part of the atoll of Abemama is linked together by causeways making automobile traffic possible between the different islets. The outlying islands of Abatiku and Biike are situated on the southwestern side of the atoll.
