Bougainville Island is the largest island within the Solomon Islands archipelago. It serves as the primary landmass for the Autonomous Region of Bougainville. This region is a part of the sovereign nation of Papua New Guinea.

The island sits within the Solomon Islands rain forests ecoregion. It is characterized by a tropical rainforest climate, known scientifically as Af on the Köppen classification. This means the weather is generally warm and wet. February is recorded as the driest month of the year on the island.

The geography of the area is shaped by volcanic activity and deep waters. The main island and the smaller Buka Island were once a single landmass. Today, they are separated by the Buka Strait, which is both deep and wide. There is no bridge connecting the two islands. Instead, a regular ferry service moves people between key settlements. Buka Island lies to the north of the main island. The highest point in the region is Mount Balbi. The island also features several volcanoes that are active, dormant, or inactive. Bagana is a conspicuously active volcano in the north-central part of the island. It frequently spews gas that is visible from many kilometers away.

Human history on Bougainville stretches back to the Last Ice Age. During that time, the area was part of a larger landmass called "Greater Bougainville." This single mass spanned from the northern tip of Buka Island to the Nggela Islands. The earliest evidence of human settlement is found at Kilu Cave on Buka Island. These remains date from between 26,700 and 18,100 BCE. The first settlers were Melanesian people. They were likely related to modern Papuans and Indigenous Australians. Later, in the 2nd millennium BCE, Austronesian people arrived. They brought domesticated animals, including pigs, chickens, and dogs, along with obsidian tools.

European contact began in 1768 with the French explorer Louis Antoine de Bougainville. He named the island after himself. In the 19th century, British and American whaling ships visited for wood, water, and provisions. The first recorded visit was by the ship Roscoe in 1822. The last was by the Palmetto in 1881. In 1899, the German Empire annexed the island into German New Guinea. During World War I, Australia occupied the territory. By 1920, it became part of the Australian Territory of New Guinea under a League of Nations mandate.

World War II brought further conflict when Japan invaded in 1942. Allied forces launched the Bougainville campaign in 1943 to regain control. During this Pacific War conflict, Japanese admiral Isoroku Yamamoto died when his plane crashed into the jungle.

The island's economy is tied to its massive natural resources. Bougainville holds one of the world's largest copper deposits. The Panguna mine has been under development since 1972. It is estimated to contain one billion tonnes of copper ore and 12 million ounces of gold. However, mining has caused significant environmental issues. A Rio Tinto-owned operation in Panguna was known for heavy metal impacts. This led to a revolution and the eventual shutdown of the mine. More recently, deforestation to support a growing population has affected river flows. The United Nations Environment Programme has offered to help clean up the Panguna mine.

Society on the island is diverse in terms of language and faith. Most residents are Christian, with 75% to 80% identifying as Roman Catholic as of 2015. Other groups include the United Church of Papua New Guinea and the Seventh-day Adventist Church. Many indigenous languages belong to three different language families. The Austronesian family includes languages like Halia, which is spoken on Buka and the Selau peninsula. Other languages include Nehan, Solos, and Hahon. For general communication, many people use Tok Pisin as a lingua franca. English and Tok Pisin are used for official government business.

Political history has been marked by significant struggle and recent change. Between 1988 and 1998, the Bougainville Civil War claimed over 15,000 lives. During this time, a blockade by Papua New Guinea cut the island off from the outside world. This lack of medical resources caused many deaths. Peace talks brokered by New Zealand in 1997 eventually led to autonomy. In 2001, a peace agreement was signed that promised a referendum on independence. In 2019, citizens voted on whether to have full independence or greater autonomy. An overwhelming 98.31% of valid votes were in favor of full independence. However, this vote is non-binding, and the government of Papua New Guinea holds the final decision.
