* '''La Amazonía''', also known as ''El Oriente'', or "the east": The oriente consists of the Amazon jungle provinces – Morona Santiago, Napo, Orellana, Pastaza, Sucumbíos, and Zamora-Chinchipe. This region is primarily made up of the huge Amazon national parks and Amerindian untouchable zones, which are vast stretches of land set aside for the Amazon Amerindian tribes to continue living traditionally. It is also the area with the largest reserves of petroleum in Ecuador, and parts of the upper Amazon here have been extensively exploited by petroleum companies. The population is primarily mixed Amerindian Shuar, Huaorani and Kichua, although there are numerous tribes in the deep jungle which are little-contacted. The largest city in the Oriente is probably Lago Agrio in Sucumbíos, although Macas in Morona Santiago runs a close second.
