Sorghum bicolor, commonly called sorghum and also known as broomcorn, great millet, Indian millet, Guinea corn, jowar, or milo, is a species in the grass genus Sorghum. It is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 metres (13 ft) high. The grain is 2 to 4 millimetres (0.08 to 0.2 in) in diameter.

The species originated and was domesticated in Sudan. Native to Africa and the Indian subcontinent, it is cultivated in tropical and subtropical regions for its grain. It is the world's fifth-most important cereal crop. The grain is used as food by humans, while the plant is used for animal feed and ethanol production.
