West Papua, formerly Irian Jaya Barat, is a province of Indonesia located in the land of Papua. It covers most of the two western peninsulas of the island of New Guinea, the eastern half of the Bird's Head Peninsula and the whole of the Bomberai Peninsula, along with nearby smaller islands. The province is bordered to the north by the Pacific Ocean, to the west by Southwest Papua Province, the Halmahera Sea and the Ceram Sea, to the south by the Banda Sea, and to the east by the province of Central Papua and the Cenderawasih Bay. Manokwari is the province's capital and largest city. With an estimated population of 561,403 in mid-2022, West Papua is the least populous province in Indonesia after Southwest Papua, which was a part of West Papua until separated off in 2022.
Western New Guinea, also known as Papua, Indonesian New Guinea, and Indonesian Papua, is the western, Indonesian half of the island of New Guinea. Since the island is alternatively named Papua, the region is also called West Papua.
Puncak Trikora, until 1963 Wilhelmina Peak, is a 4,730 or 4,750-metre-high (15,584 ft) mountain in the Highland Papua province of Indonesia on New Guinea. It lies in the eastern part of the Sudirman (Nassau) Range of the Maoke Mountains.
Frans Kaisiepo was a Papuan politician and Indonesian nationalist. He served as the fourth Governor of Papua Province. In 1993, Kaisiepo was posthumously declared a National Hero of Indonesia for his lifelong efforts to unite West Irian with Indonesia.

The Kaure–Kosare or Nawa River languages are a small family spoken along the Nawa River in West Papua, near the northern border with Papua New Guinea. The languages are Kaure and Kosare.
The Dani or Baliem Valley languages are a family of clearly related Trans–New Guinea languages spoken by the Dani and related peoples in the Baliem Valley in the Highland Papua, Indonesia. Foley (2003) considers their Trans–New Guinea language group status to be established. They may be most closely related to the languages of Paniai Lakes, but this is not yet clear. Capell (1962) posited that their closest relatives were the Kwerba languages, which Ross (2005) rejects.
The Ok languages are a family of about a dozen related Trans–New Guinea languages spoken in a contiguous area of eastern Irian Jaya and western Papua New Guinea. The most numerous language is Ngalum, with some 20,000 speakers; the best known is probably Telefol.
New Guinea is the world's second-largest island, with an area of 785,753 km2 (303,381 sq mi). Located in Melanesia in the southwestern Pacific Ocean, the island is separated from Australia by the 150-kilometre wide Torres Strait, though both landmasses lie on the same continental shelf, and were united during episodes of low sea level in the Pleistocene glaciations as the combined landmass of Sahul. Numerous smaller islands are located to the west and east. The island's name was given by Spanish explorer Yñigo Ortiz de Retez during his maritime expedition of 1545 due to the resemblance of the indigenous peoples of the island to those in the African region of Guinea.
The West Trans–New Guinea languages are a suggested linguistic linkage of Papuan languages, not well established as a group, proposed by Malcolm Ross in his 2005 classification of the Trans–New Guinea languages. Ross suspects they are an old dialect continuum, because they share numerous features that have not been traced to a single ancestor using comparative historical linguistics. The internal divisions of the languages are also unclear. William A. Foley considers the TNG identity of the Irian Highlands languages at least to be established.

Dem is a divergent Papuan language of West New Guinea. Although Palmer (2018) leaves it unclassified, it was tentatively included in the Trans–New Guinea family in the classification of Malcolm Ross (2005), and Timothy Usher ties it most closely to Amung.

The West New Guinea dispute (1950–1962), also known as the West Irian dispute, was a diplomatic and political conflict between the Netherlands and Indonesia over the territory of Dutch New Guinea. While the Netherlands had ceded sovereignty over most of the Dutch East Indies to Indonesia on 27 December 1949 following an independence struggle, it retained control over its colony on the western half of New Guinea. The Indonesian government claimed this territory as well, on the basis that it had belonged to the Dutch East Indies and that the new Republic of Indonesia was the legitimate successor to the former Dutch colony.
