Papua New Guinea, officially the Independent State of Papua New Guinea, is an Oceanian country that occupies the eastern half of the island of New Guinea and its offshore islands in Melanesia, a region of the southwestern Pacific Ocean north of Australia. Its capital, located along its southeastern coast, is Port Moresby. The western half of New Guinea forms the Indonesian provinces of Papua and West Papua.
The country is situated on the Pacific Ring of Fire, at the point of collision of several tectonic plates. There are a number of active volcanoes, and eruptions are frequent. Earthquakes are relatively common, sometimes accompanied by tsunamis. Papua New Guinea is one of the few regions close to the equator that experience snowfall, which occurs in the most elevated parts of the mainland.

Papua New Guinea has more languages than any other country, with over 820 indigenous languages, representing 12% of the world's total, but most have fewer than 1,000 speakers. The most widely spoken indigenous language is Enga, with about 200,000 speakers, followed by Melpa and Huli. Indigenous languages are classified into two large groups, Austronesian languages and non-Austronesian, or Papuan, language. There are three official languages for Papua New Guinea: English, Tok Pisin, and Hiri Motu.
The courts and government practice uphold the constitutional right to freedom of speech, thought, and belief, and no legislation to curb those rights has been adopted. The 2000 census found that 96% of citizens identified themselves as members of a Christian church; however, many citizens combine their Christian faith with some traditional indigenous religious practices.
