Papua Province (Indonesian: Provinsi Papua) is the largest and easternmost province of Indonesia. It lies in West Papua region, which comprises the Indonesian, western, half of the island of New Guinea and nearby islands. Papua is bordered by the nation of Papua New Guinea to the east, and by West Papua province to the west. Its capital is Jayapura. It was formerly called Irian Jaya (before that West Irian or Irian Barat) and comprised all of Indonesian New Guinea. In 2002 the current name was adopted and in 2003 West Papua province was created within West Papua region from western parts of Papua province.
"Papua" is the official Indonesian and internationally recognised name for the province.
During the Dutch colonial era the region was known as part of "Dutch New Guinea" or "Netherlands New Guinea". Since its annexation in 1969, it became known as "West Irian" or "Irian Barat" until 1973, and thereafter renamed "Irian Jaya" (roughly translated, "Glorious Irian") by the Suharto administration. This was the official name until the name "Papua" was adopted in 2002. Today, the indigenous inhabitants of this province prefer to call themselves Papuans.
