city, western Gabon. It is located on Lopez Island (in the mouth of the navigable Ogooué River) and on a bay sheltered by Cape Lopez, which juts into the Atlantic Ocean. The nation's chief port and industrial centre, it is linked by air with Paris and major West African centres as well as with many Gabonese towns.

The Portuguese navigator Lopo Gonçalves first rounded Cape Lopez in 1473. By the end of the 19th century several commercial houses were established there, and okoume wood (Gabonese mahogany) was exported. The discovery of oil offshore at nearby Ozouri and Pointe Clairette in 1956 stimulated Port-Gentil's commercial and industrial growth. A petroleum port was constructed, and an oil refinery and training school for the workers opened at Pointe Clairette. In addition, sawmilling and the production of plywood and veneer are also important. In addition to okoume, ebony and kevazingo woods and other products from Ndjolé and Lambaréné on the Ogooué River are shipped to Port-Gentil for export. Other industries include a brewery, a construction company, a chemical plant, and factories for making furniture and for processing fish, rice, and palm oil. Port-Gentil was severely damaged by antigovernment rioting in May 1990. Pop. (2003 est.) 116,200.
