Gabon (; French pronunciation: ​[ɡabɔ̃]; Sangu: Ngabu), officially the Gabonese Republic (French: République gabonaise), is a country on the west coast of Central Africa. Located on the equator, it is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly 270,000 square kilometres (100,000 sq mi) and its population is estimated at 2.3 million people. There are coastal plains, mountains (the Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east.

Since its independence from France in 1960, the sovereign state of Gabon has had three presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more transparent electoral process and reformed some governmental institutions. Despite this, the Gabonese Democratic Party (PDG) remains the dominant party. With petroleum and foreign private investment, it has the fourth highest HDI in the region (after Mauritius, Seychelles and South Africa) and the fifth highest GDP per capita (PPP) in all of Africa (after Seychelles, Mauritius, Equatorial Guinea and Botswana). Its GDP grew by more than 6% per year from 2010 to 2012.

The official language is French. Bantu ethnic groups constitute around 95% of the country's population, and Christianity is the most practiced religion, being practiced by between 55–75% of the population.
