准谷物，也称为假谷物，是和谷物一样可以作为粮食的阔叶植物（非禾本科）。其种子可以磨成粉或是像谷物一样食用。常见的准谷物有苋属植物（尾穗苋、红苋菜、千穗谷）、藜麦及荞麦.

Pseudocereals are non-grasses that are used in much the same way as cereals (true cereals are grasses). Their seed can be ground into flour and otherwise used as cereals. Examples of pseudocereals are amaranth (Love-lies-bleeding, red amaranth, Prince-of-Wales-feather), quinoa, and buckwheat.
