Rhopalostylis is a genus of palms native to the South Pacific. All three palms are smooth-trunked, with regular ringed scars from fallen leaves. The leaves are 3-5 meters in length, and the leaf bases encircle the trunk.

Rhopalostylis has the southernmost range of any palm genus. R. sapida, known as the Nikau Palm, is New Zealand's only native palm species, and is found in lowland forests on the North Island and on the Chatham Islands. R. cheesemanii is endemic to the Kermadec Islands northeast of New Zealand. R. baueri is endemic to Norfolk Island.
