Yam is the common name for some plant species in the genus Dioscorea (family Dioscoreaceae) that form edible tubers. Yams are perennial herbaceous vines cultivated for the consumption of their starchy tubers in many temperate and subtropical world regions. The tubers themselves are also called "yams", having numerous cultivars and related species.


In parts of the United States and Canada, "yam" is sometimes used to refer to varieties of the unrelated sweet potato.
