Arachis is a genus of about 70 species of annual and perennial flowering plants in the pea family (Fabaceae), native to South America. At least one species, the peanut (Arachis hypogaea), is a major food crop species of global importance; some of the other species are cultivated for food to a small extent in South America. Other species such as A. pintoi are cultivated worldwide as forage and soil conditioner plants, with the leaves providing high-protein feed for grazing livestock and a nitrogen source in agroforestry and permaculture systems.

Arachis species, including the peanut, are used as food plants by some Lepidoptera species, including flame shoulder, nutmeg and turnip moths.^{[citation needed]}
