南美象龜屬（Chelonoidis）是陸龜科下的一個屬。 該書的龜發現於加拉帕戈斯群島和南美洲各地。以前被認為是象龜屬（Geochelone）的成員，但最近的基因證據顯示其血緣關係與折背龜屬更接近。 它們的祖先在漸新世穿過大西洋來到美洲， 這可能要歸功於它們可以把頭露出水面漂浮并可以六個月不吃不喝的能力。 其下的加拉帕戈斯象龜是世界上現存最大的陸龜，這些大型龜類在更新世時就已近在南北大陸上繁衍了。

Chelonoidis is a genus of turtles in the tortoise family erected by Leopold Fitzinger in 1835. They are found in South America and the Galápagos Islands, and formerly had a wide distribution in the West Indies.
The multiple subspecies of the Galápagos tortoise (C. niger) are among the largest extant terrestrial chelonians. Giant members of the genus, such as Lutz's giant tortoise (C. lutzae) were also present in mainland South America and the West Indies during the Pleistocene, and the latter into the Holocene.
