Gesneria is a genus of flowering plants in the family Gesneriaceae. It contains 62 species which are native to islands of the Caribbean. The genus is classified in the tribe Gesnerieae along with the genera Bellonia, Pheidonocarpa, and Rhytidophyllum. Gesneria species are usually woody shrubs or subshrubs, and (with the closely related Rhytidophyllum) are unusual in the family in having alternately (rather than decussately) arranged leaves. A complete list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.

The genus name honors Conrad Gessner.
