The lentil (Lens culinaris or Lens esculenta) is an edible legume. It is a bushy annual plant known for its lens-shaped seeds. It is about 40 cm (16 in) tall, and the seeds grow in pods, usually with two seeds in each.

In cuisines of the Indian subcontinent, split lentils (often with their hulls removed) are often cooked into a thick gravy that is usually eaten with rice or rotis, the lentil is a dietary staple throughout the Indian subcontinent. As a food crop, the majority of world production comes from Canada, India, and Turkey.
