Coccothrinax alta (also known in Puerto Rican Spanish as palma plateada or palma de abanico,[2] or in the Virgin Islands as Tyre palm)[3] is a palm which is native to Puerto Rico and the Virgin Islands.

George Proctor (in Acevedo-Rodríguez & Strong, 2005[2]) considers this to be a valid species on the basis of its shorter, more slender trunk, fewer stamens and much smaller fruit.

Rafaël Govaerts[4] follows Read (1979) and considers it a synonym of Coccothrinax barbadensis.

Trees are 2–6 m tall, with some individuals getting up to 11 m. Flowers are light yellow, and fruit are purple-black when ripe.

[2] It is found on limestone substrates in northern Puerto Rico, and on volcanic substrates on the islands off eastern Puerto Rico.
