象耳豆（学名：Enterolobium cyclocarpum）为豆科象耳豆属下的一个种。

Enterolobium cyclocarpum, commonly known as guanacaste, caro caro, or elephant-ear tree, is a species of flowering tree in the pea family, Fabaceae, that is native to tropical regions of the Americas, from central Mexico south to northern Brazil (Roraima) and Venezuela. It is known for its large proportions, its expansive, often spherical crown, and its curiously shaped seedpods. The abundance of this tree, especially in Guanacaste Province, Costa Rica, where it is prized for the shady relief it provides from the intense sun, coupled with its immensity, have made it a widely recognized species. It is the national tree of Costa Rica.
