Thrinax is a genus in the palm family, native to the Caribbean. It is closely related to the genera Coccothrinax, Hemithrinax and Zombia.{{cite book |last=Henderson |first=Andrew |author-link= Andrew Henderson (botanist) |author2=Gloria Galeano |author2-link=Gloria Galeano |author3=Rodrigo Bernal |author3-link=Rodrigo Bernal |title=Field Guide to the Palms of the Americas |year=1995 |publisher=Princeton University Press |location=Princeton, New Jersey | isbn=978-0-691-08537-1 }} Flowers are small, bisexual and are borne on small stalks.

In the first edition of Genera Palmarum (1987), Natalie Uhl and John Dransfield placed the genus Thrinax in subfamily Coryphoideae, tribe Corypheae and subtribe Thrinacinae.{{cite book |last= Uhl |first= Natalie E. |author2=John Dransfield |title=Genera Palmarum: a classification of palms based on the work of Harold E. Moore Jr |year=1987 |publisher=The L. H. Bailey Hortorium and the International Palm Society|location=Lawrence, Kansas}} Subsequent phylogenetic analyses showed that the Old World and New World members of Thrinacinae are not closely related and as a consequence, Thrinax and related genera were transferred into their own tribe, Cryosophileae.{{cite journal| last = Dransfield| first = John|author2=Natalie W.
