Ungnadia speciosa, the Mexican Buckeye, is a shrub or small tree native to northeastern Mexico and adjacent western Texas and southern New Mexico in the United States. It is monotypic, the only species in the genus Ungnadia.
It differs from the buckeyes in the related genus Aesculus in having alternate, pinnate leaves with 5-7 leaflets, but the flowers and nuts are similar. Another similar related genus is the soapberry (genus Sapindus).
