Ogooué-Ivindo Province is the northeasternmost of Gabon's nine provinces, though its Lopé Department is in the very center of the country. It gets its name from two rivers, the Ogooué and the Ivindo. This province, containing thousands of square kilometres of rainforest, is the largest and most sparsely populated and much less developed than the rest of the country. As of 2013 it had a population of 63,293 people. The principal town is Makokou.

Booué is a small town in central Gabon. It is situated in Lopé Department, southwest side of the Ogooué-Ivindo Province. The town lies just 6.6 miles to the south of the Equator and is the province's only Department capital in the Southern Hemisphere.
