Roystonea regia, commonly known as the Cuban royal palm, Florida royal palm, or simply the royal palm is a species of palm which is native to southern Florida, Mexico and parts of Central America and the northern Caribbean. It ranged into central Florida in the eighteenth century but in modern times it is only known from tropical parts of south Florida. A large and attractive palm, it has been planted throughout the tropics and subtropics as an ornamental tree. Although it is sometimes called R. elata, the conserved name R. regia is now the correct name for the species. Populations in Cuba and Florida were long seen as separate species, but are now considered to belong to a single species.
Best known as an ornamental, R. regia is also used as a source of thatch, construction timber, and as a medicinal plant. The fruit is eaten by birds and bats (which disperse the seeds) and fed to livestock. Its flowers are visited by birds and bats, and it serves as a roosting site and food source for a variety of animals.
