Kanton Island (also known as Canton Island or Abariringa Island), alternatively known as "Mary Island", "Mary Balcout's Island" or "Swallow Island", is the largest, northernmost, and as of 2007[update], the sole inhabited island of the Phoenix Islands, in the Republic of Kiribati. It is an atoll located in the South Pacific Ocean roughly halfway between Hawaii and Fiji at 2°50′S 171°40′W / 2.833°S 171.667°W. The island is a narrow ribbon of land enclosing a lagoon with an area of 40 square kilometers. Kanton's closest neighbor is the uninhabited island of Enderbury, 63 km to the south. The capital of Kiribati, South Tarawa, lies 1,765 km to the west. As of 2005[update], the population was 41, down from 61 in 2000. In May 2010 the population was reportedly 24, with 14 adults and 10 children. The island's sole village is called Tebaronga.
Kiribati declared the Phoenix Islands Protected Area in 2006, with the park being expanded in 2008. The 164,200-square-mile (425,300-square-kilometer) marine reserve contains eight coral atolls including Kanton.
The first recorded sighting by Europeans was in September 1595 by the second Spanish expedition of Álvaro de Mendaña. More precisely it was sighted by Lorenzo Barreto while in command of one of the smaller vessels on a local voyage round the then called Santa Cruz, which is today's Nendo Island.
