Zanthoxylum atchoum (synonym Fagara atchoum) is a forest tree in the Rutaceae family that grows in Côte d'Ivoire's Eastern Guinean forests. It is endemic to Côte d'Ivoire where it is threatened by habitat loss. Waterman assigned Z. atchoum to this combination after morphological and secondary metabolite evidence revealed that Fagara should be subsumed in Zanthoxylum.
