糯稻（学名：Oryza sativa var. glutinosa），禾本科一年生草本植物，是稻的粘性变种，在籼稻和粳稻品种中都有糯稻变种，糯稻脱壳的米在中国南方称为糯米（闽南语、闽东语、莆仙语皆称“秫米”），而北方则多称为江米，是制造粘性小吃，如粽、八宝粥、各式甜品的主要原料。《西京杂记》载，汉代有九月九日吃蓬饵之俗，“九月九日，佩茱萸、食蓬饵、饮菊花酒、食人长寿。”“食蓬饵以祓妖邪。”饵即古代之糕，原料是米粉，可以是稻米粉或黍米粉。糯米也是酿造醪糟（甜米酒）的主要原料。

在外貌上，糯米为不透明的白色。糯米与其他稻米的最主要分别是它所含的淀粉中以枝链淀粉为主，达95%至100%，因而煮后较具黏性。

Glutinous rice (Oryza sativa var. glutinosa; also called sticky rice, sweet rice or waxy rice) is a type of rice grown mainly in Southeast and East Asia, which has opaque grains, very low amylose content, and is especially sticky when cooked. It is called glutinous (< Latin glūtinōsus) in the sense of being glue-like or sticky, and not in the sense of containing gluten. While often called "sticky rice", it differs from non-glutinous strains of japonica rice which also become sticky to some degree when cooked. There are numerous cultivars of glutinous rice, which include japonica, indica, and tropical japonica strains.
