'''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。<ref name = "Le et al.">{{cite journal | last = Le | first = M. | authorlink =  | coauthors = Raxworthy, C.

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。
