黍（学名：Panicum miliaceum），是禾本科黍属的一类种子形小的饲料作物和谷物。一年生草本植物，植株叫黍子，生长期短，耐寒耐旱耐贫瘠；籽实叫黍，淡黄色；磨米去皮后称黍米，俗称黄米，为黄色小圆颗粒，直径大于粟米（即北方俗称的小米）；黍米再磨成面，俗称黄米面。黍的籽粒有粳性与糯性之分。粳性黍为非糯质，不黏，一般供食用。糯性黍为糯质，性黏，磨米去皮后称作大黄米或软黄米，用途广泛，可磨面作糕点，古代也广泛用于酿酒。在中国黍子栽培大体以山西-陕西省界（约为东经110度）为界，以东的华北、东北地区以糯性黍子为主，以西的陕西、甘肃、宁夏等地以粳性黍子为主。

Panicum miliaceum (Kannada:ಬರಗು), with many common names including proso millet, broomcorn millet, common millet, broomtail millet, hog millet, red millet, and white millet, is a grass species used as a crop. Both the wild ancestor and location of the original domestication of proso millet are unknown, but it first appears as a crop in both Transcaucasia and China about 7,000 years ago, suggesting it may have been domesticated independently in each area. It is still extensively cultivated in India, Russia, Ukraine, the Middle East, Turkey and Romania. In the United States, proso is mainly grown for birdseed. It is sold as health food, and due to its lack of gluten, it can be included in the diets of people who cannot tolerate wheat.
