Wedelia is a genus of flowering plants in the family Asteraceae.

[6] The genus is named in honor of German botanist and physician Georg Wolfgang Wedel, 1645–1721.

Further studies are needed to clarify its taxonomic and phylogenetic relationships.

[9][10] Many species were once considered part of Wedelia but have been now transferred to other genera, including Angelphytum, Aspilia, Baltimora, Blainvillea, Chrysogonum, Eclipta, Elaphandra, Eleutheranthera, Guizotia, Heliopsis, Kingianthus, Lasianthaea, Melampodium, Melanthera, Moonia, Sphagneticola, Synedrella, Tuberculocarpus, Verbesina, Viguiera, Villanova, Wollastonia and Zexmenia.
