Vigna is a genus of plants in the legume family, Fabaceae, with a pantropical distribution.

According to Hortus Third, Vigna differs from Phaseolus in biochemistry and pollen structure, and in details of the style and stipules.

Vigna is also commonly confused with the genus Dolichos, but the two differ in stigma structure.

The genus is named after Domenico Vigna, a seventeenth-century Italian botanist and director of the Orto botanico di Pisa.

[5] Root tubers of Vigna species have traditionally been used as food by the Indigenous Peoples of the Northern Territory.
