A new species Trachycarpus ravenii discovered in Kasi district, Vientiane province of central Laos is described and illustrated. Morphologically, it is closest to T. oreophilus and T. princeps , but differs by having a shorter stem of mature plants; glabrous, dull green petiole; almost circular leaf blade, waxy bluish–white abaxially; narrow leaf segments with narrow free lobes densely adpressed to each other, as well as in oblique‐round apices of median leaf segments.
