Besleria is a genus of ca. 200 species of large herbs and soft-stemmed subshrubs or shrubs in the flowering plant family Gesneriaceae. They occur in Central America, South America, and the West Indies.
The closely related genus Gasteranthus was previously included in Besleria. The two genera have been separated on the basis of stomatal (aggregated in Gasteranthus, scattered in Besleria) and fruit (fleshy capsule in Gasteranthus, berry in Besleria) characters.
