Frodinia tremula is a species of plant in the family Araliaceae.

It is a scrambling tree endemic to the island of Hispaniola (in the Dominican Republic and Haiti).

[1] Frodinia tremula is the predominant tree in the montane cloud forests of Pic Macaya National Park in the Massif de la Selle of southwestern Haiti.

It grows with small trees and shrubs including Garrya fadyenii, Myrsine coriacea, Brunellia comocladiifolia, Persea hypoleuca, Weinmannia pinnata, Cestrum coelophlebium, and Miconia spp., the tree ferns Cyathea harrisii and Alsophila minor, and the climbing bamboo Arthrostylidium haitiense.

Fires kill the young broadleafed trees, and favor the germination of pines.
