亚马孙雨林（英语：Amazon Rainforest），又称亚马逊河雨林，位于南美洲亚马逊盆地的热带雨林，占地700万平方公里（7亿公顷），使这片雨林生机盎然的就是亚马逊河。雨林横越了8个国家：巴西（占森林60%面积）、哥伦比亚、秘鲁、委内瑞拉、厄瓜多尔尔、玻利维亚、圭亚那及苏里南，包括法属圭亚那。其中4个国家将雨林所属州份取名亚马逊州。亚马逊雨林占世界雨林面积的一半，森林面积的20%，是全球最大及物种最多的热带雨林。

The Amazon rainforest (Portuguese: Floresta Amazônica or Amazônia; Spanish:Selva Amazónica, Amazonía or usually Amazonia; French:Forêt amazonienne; Dutch:Amazoneregenwoud), also known in English as Amazonia or the Amazon Jungle, is a moist broadleaf forest that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 square kilometres (2,700,000 sq mi), of which 5,500,000 square kilometres (2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana. States or departments in four nations contain "Amazonas" in their names. The Amazon represents over half of the planet's remaining rainforests, and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees divided into 16,000 species.
