Hymenaea mexicana is an extinct legume species in the family Fabaceae described from a series of isolated fossil petals, leaflets, and amber.

The species is known from a group of Late Oligocene to Early Miocene locations in southern Mexico.

[1] Hymenaea mexicana is known from a series of fossil flowers and leaves which are inclusions in transparent chunks of Mexican amber.

[1] Mexican amber is recovered from fossil-bearing rocks in the Simojovel region of Chiapas, Mexico.

[3] The fossils were examined by paleobotanists George Poinar Jr. of Oregon State University and Alex Brown of Berkeley, California; Poinar and Brown's description of the species was published in a 2002 article in the Botanical Journal of the Linnean Society.
