Cumin (/ˈkjuːmɪn/ or UK: /ˈkʌmɪn/, US: /ˈkuːmɪn/) (Cuminum cyminum) is a flowering plant in the family Apiaceae, native to a territory including Middle East and stretching east to India. Its seeds – each one contained within a fruit, which is dried – are used in the cuisines of many cultures in both whole and ground form. Although cumin is thought to have uses in traditional medicine, there is no high-quality evidence that it is safe or effective as a therapeutic agent.

Cumin is the dried seed of the herb Cuminum cyminum, a member of the parsley family. The cumin plant grows to 30–50 cm (12–20 in) tall and is harvested by hand. It is an annual herbaceous plant, with a slender, glabrous, branched stem that is 20–30 cm (8–12 in) tall and has a diameter of 3–5 cm (​1 1⁄4–2 in). Each branch has two to three subbranches. All the branches attain the same height, so the plant has a uniform canopy. The stem is coloured grey or dark green. The leaves are 5–10 cm (2–4 in) long, pinnate or bipinnate, with thread-like leaflets. The flowers are small, white or pink, and borne in umbels. Each umbel has five to seven umbellets. The fruit is a lateral fusiform or ovoid achene 4–5 mm (​1⁄6–​1⁄5 in) long, containing two mericarps with a single seed. Cumin seeds have eight ridges with oil canals. They resemble caraway seeds, being oblong in shape, longitudinally ridged, and yellow-brown in colour, like other members of the Apiaceae (Umbelliferae) family such as caraway, parsley, and dill
