高粱（学名：Sorghum bicolor）又名二色高粱、蜀黍，禾本科，一年生高大草本植物，原产于非洲，喜温、抗旱、耐涝，种子有红、白、褐各种颜色，有粘性变种。按用途分有食用、帚用、糖用和草用几类。幼苗期类似玉米，但其新鲜茎、叶含有氰化类剧毒，要用作饲料必先经过贮藏阴干。

在中国东北高粱的种植相当普遍，由于其茎高大可以**，高梁地又俗称为「青纱帐」。高粱其他主要产区有美国、非洲和南亚，可以用作饲料。在世界粮食作物种植面积中占第五位(前四位依次为玉米、小麦、稻、大麦)。

高粱淀粉含量高，酿酒没有其他干扰味道，适合酿造中国白酒，中国白酒中质量最高的品牌几乎都是主要用高粱酿造的。 高粱曾经在晋语区是主要的粮食作物，人们将高粱米蒸煮成米饭食用，也将成熟的高粱种子磨制成面粉（红面）用以加工面条食品。近年来多用于酿造。

Sorghum bicolor, commonly called sorghum (/ˈsɔːrɡəm/) and also known as great millet, durra, jowari, or milo, is a grass species cultivated for its grain, which is used for food, both for animals and humans, and for ethanol production. Sorghum originated in northern Africa, and is now cultivated widely in tropical and subtropical regions. Sorghum is the world's fifth most important cereal crop after rice, wheat, maize and barley. S. bicolor is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 m high. The grain is small, ranging from 3 to 4 mm in diameter. Sweet sorghums are sorghum cultivars that are primarily grown for foliage, syrup production, and ethanol; they are taller than those grown for grain.
