Rhopalostylis is a genus of two species of palms native to the South Pacific.
Both are smooth-trunked, with regular ringed scars from fallen leaves.
The leaves are 3–5 m in length, and the leaf bases encircle the trunk.
Subfamily: Arecoideae; tribe: Areceae; subtribe: Rhopalostylidinae.
Rhopalostylis is closely related to the Lord Howe Island genus Hedyscepe.
