Abrus is a genus of flowering plants in the pea family, Fabaceae, and the only genus in the tribe Abreae. It contains 13–18 species, but is best known for a single species: jequirity (A. precatorius). The highly toxic seeds of that species are used to make jewellery.

Species range naturally across tropical Africa, Madagascar, the Arabian Peninsula, south and southeast Asia, southern China, New Guinea, and Australia. Some species have been introduced to the tropical Americas.
