West Papua, formerly Irian Jaya Barat, is an Indonesian province located in Indonesia 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 569,570 in mid-2023, West Papua is the least populous province in Indonesia after South Papua, following the separation off in 2022 of the western half of the Bird's Head Peninsula to create the new province of Southwest Papua, containing 52% of what had been West Papua's population. Its population density is similar to Russia.
Western New Guinea, also known as Papua, Indonesian New Guinea, and Indonesian Papua, is the western half of the island of New Guinea, formerly Dutch and granted to Indonesia in 1962. Given the island is alternatively named Papua, the region is also called West Papua.

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.

It is made up of an isolated and lesser continuous mountain chain compared to the Arfak Mountains. The Tamrau and Arfak Mountains are both divided by the grassy Kebar Valley, which is the heartland of many indigenous people, with a variety of backgrounds. The Tamrau Mountains have been scantily surveyed. The mountains are an important and threatened site of biodiversity, part of the Vogelkop montane rain forests ecoregion.

The valley is enclosed by the fault-bounded Tamrau Mountains at an area of 2,703 square kilometres (1,044 sq mi). Its depth averages from 500 to 600 m in the lower sections to around 900 to 1,400 m in the upper sections of the valley. The valley is located 130 km (81 mi) west of Manokwari and 190 km (120 mi) east of Sorong. The nearest major village to the valley is Saukorem. A notable path runs through the Kebar Valley connecting Saukorem to the settlement of Andai and reaches an altitude of 1,200 m (3,900 ft). This has created many villages throughout the area, leading to a growing rice production in the central and eastern regions of the valley. From north to south, the Kebar Valley ranges from 16 to 30 km wide, and from east to west, it extends from 94 to 116 km in length.

Southwest Papua is the 38th province of Indonesia to be created, and was split off from West Papua on 8 December 2022. Despite being named southwest, it is a misnomer and this province is actually located in the northwest edge of Papua. The province comprises the Greater Sorong area which consists of Sorong City, Sorong Regency, South Sorong Regency, Maybrat Regency, Tambrauw Regency, and Raja Ampat Regency. The Bill (RUU) on the Establishment of the Southwest Papua Province was passed into law and therefore it became the 38th province in Indonesia with effect from 8 December 2022.
