Ventilago is a genus of plants in the family Rhamnaceae. It includes about 40 species found in the tropics of South and SE Asia, Australasia, with one species each in Africa and Madagascar.
Plants in this genus are evergreen vines, scandent shrubs, or (rarely) small trees. Inflorescences emerge from the leaf axils and may consist of solitary flowers or glomerules. Petals are absent in some species, e.g. Ventilago ecorollata. The fruit is a single-seeded samara with a wing attached at the apex.
The roots of Ventilago vanuatuana—included in Ventilago neocaledonica before 2020—are used in Vanuatu to produce a crimson red dye (Apma: laba) which is used to pattern traditional textiles.
As of December 2025[update], Plants of the World Online accepts the following 40 species:
