Annona moaensis is a species of plant in the family Annonaceae. It is endemic to Cuba.[1] Frère León and Henri Alain Liogier, the botanists who first formally described the species, named it after Moa, Cuba where the specimen they observed was collected.

It is a bush reaching 2–3 meters in height. Its branches have white lenticels. Its leaves are 5-9 by 1-2 centimeters and come to tapering point. The upper surface of the leaves are glossy, the undersides are lightly covered in wooly hairs. The leaves have 18-20 secondary veins emanating from its midrib. Its petioles are 3-6 millimeters long, covered in rust-colored wooly hairs and have a groove on their upper surface. Its flowers are on 1-1.5 centimeter long, black peduncles that are covered in white wooly hairs. The peduncles have a triangular bract about a third of the way up their length. The bract is covered with rust-colored wooly hairs. Its calyx has triangular lobes. It has 3 petals that touch, but are not fused, at their margins. The petals are 20-25 by 3 millimeters and a bit wider at their base. The petals reddish on their outer surface and have wooly hairs on both surfaces.
