A species of Thai Ilex (Aquifoliaceae), I. inthanonensis, is reported new to science. Ilex inthanonensis is glabrous on most parts except puberulent in the infructescences, leaf blade punctate below, fruiting pedicels shorter than or equalling fruit diameter, calyx 4–5-lobed, pyrenes 4–5 with 3–5(–6)-striae slightly elevated dorsally, not sulcate and laterally smooth. A morphological description is provided, just like photos and a line drawing. The new species is critically compared the most resembling species.
