糖高粱，俗名“甜芦粟”或“芦穄”，属禾本科高粱属，是粒用高粱的一个变种。

糖高粱形状同高粱类似，叶青灰色，茎杆中有含糖汁液。糖高粱对土壤和气候要求不严格，分布广泛，是糖料作物之一，也可用作饲料、酿酒等用途。中国各地均有出产，尤以上海崇明县为多，当地号称“芦粟之乡”。明正德（1506年-1521年）年间编修的《崇明县志》上就有记载。夏秋时收获，如甘蔗一样食用杆茎，也可埋入土中储存到冬天及春节前后食用。上海崇明方言称“芦穄 (Lu Ji)”，上海话称“甜芦粟”。甜芦粟的子与高粱结的子有所区别，前者呈扁的鸡心状，一般不食用，而高粱子呈圆形，可收获食用。还有一品种称“高粱芦穄”，既能用其茎，也能收获其子，但甜度不高，所以已很少种植。

Sweet sorghum is any of the many varieties of the sorghum grass whose stalks have a high sugar content. Sweet sorghum thrives better under drier and warmer conditions than many other crops and is grown primarily for forage, silage, and syrup production. Sweet sorghum syrup is sometimes called "molasses" or "sorghum molasses" in some regions of the U.S., but the term molasses more properly refers to a different sweet syrup, made as a byproduct of sugarcane or sugar beet sugar extraction.
