食用蕈或称食用菌或食用菇是可以食用的大型真菌子实体（不包括酵母菌、青霉菌等微生物）。决定真菌是否可以食用的因素包括毒性、味道、硬度、和气味。有些有毒的蕈类经过特定的处理（例如煮熟）后也可以食用。人类食用各种食用蕈的主要原因包括当作食物以及（特别是在民俗疗法中）当作药物。有些有致幻效果的蕈类（例如迷幻蘑菇）被用作娱乐和宗教用途食用，但食用这些菇通常会造成不适，所以一般不被视为可食用蕈。食用蕈包括许多野外采集和人工种植的物种，可能生长在木头上、寄生在其他生物上、地表、或地底下。容易种植或采集的物种常能在市场上购得，而较不易取得的（如松露和松茸）则只能小规模采收。

Edible mushrooms are the fleshy and edible fruit bodies of several species of macrofungi (fungi which bear fruiting structures that are large enough to be seen with the naked eye). They can appear either below ground (hypogeous) or above ground (epigeous) where they may be picked by hand. Edibility may be defined by criteria that include absence of poisonous effects on humans and desirable taste and aroma.
