Ulmus mexicana (Liebm.) Planch., the Mexican elm, is a large tree endemic to Mexico and Central America. It is most commonly found in cloud forest and the higher elevations (800–2200 m) of tropical rain forest with precipitation levels of 2–4 m per annum, ranging from San Luis Potosi south to Chiapas in Mexico, and from Guatemala to Panama beyond. Natural regeneration is poor. The tree was first described botanically in 1873.
