Groundnut (Arachis hypogaea), also known as peanut, is an edible legume crop grown mainly for its oil-rich seeds. Native to South America, groundnuts are now cultivated worldwide in tropical and subtropical regions. The plant grows close to the ground, with its pods developing underground after pollination.

Groundnuts have a thin, papery shell encasing two or three kernels, which are rich in protein, healthy fats, vitamins, and minerals. They are consumed raw, roasted, boiled, or processed into peanut butter, oil, flour, and confectionery products.

Known for their nutty flavor and versatility, groundnuts are a major source of plant-based nutrition and an important ingredient in culinary and industrial applications.
