Map showing West New Guinea region

Western New Guinea is the western half of the island of New Guinea. As of 2006, it is internationally recognised as Papua, a province of Indonesia. It was previously known by various names, including Netherlands New Guinea (until 1962), West Irian (1962-1973), and Irian Jaya (1973-2000). The incorporation of western New Guinea remains controversial in some quarters, including some within the area itself, and those who do not recognise the legal issues of Indonesia's claim to the area, calling it West Papua.
