Wigandia is a genus of flowering plants within the waterleaf subfamily, Hydrophylloideae. They are found mainly in Central America and South America, though one or two species are found as far north as the United States. Some are grown as ornamental plants and will flourish in most Mediterranean or temperate regions. The genus is named for Johann Wigand (ca. 1523-1587), German Lutheran cleric and theologian, and Bishop of Pomesania.

Some species originally classified in Wigandia are now treated in other genera, e.g. Eriodictyon. There is a group of closely related genera within the Hydrophylloideae subfamily, and it is likely that further taxonomic work will result in additional reclassifications. A recent molecular phylogenetic analysis of the Hydrophylloideae included two Wigandia species (W. caracasana and W. urens), and confirmed that they lay within a clade that includes Eriodictyon, and also the genera Nama and Turricula.
The genus as currently recognized comprises over 20 species, including the following:
- Wigandia brevistyla Cornejo
- Wigandia caracasana
- Wigandia crispa
- Wigandia darii
- Wigandia disparaginoides
- Wigandia ecuadorensis Cornejo
- Wigandia ericodes
- Wigandia herbacea
- Wigandia imperialis
- Wigandia kraussii
- Wigandia kunthii
- Wigandia lasiocarpa
- Wigandia laxifolia
- Wigandia leucocephala
- Wigandia macrophylla
- Wigandia peruviana
- Wigandia pruritiva
- Wigandia reflexa
- Wigandia scorpioides
- Wigandia seriphiodes
- Wigandia urens
- Wigandia vigieri
- Wigandia wurdackiana
Species formerly classified within Wigandia include:
- Eriodictyon californicum (formerly W. californica)
