松露（英语：Truffle）是一种蕈类，和蘑菇、灵芝一样都是真菌。分类为子囊菌门西洋松露科西洋松露属（学名：Tuber），大约有10种不同的品种。松露多数在阔叶树的根部着丝生长，散布于树底120～150公分方圆，块状主体藏于地下5～40公分。松露是菌根真菌，因此通常易在与树木的根部紧密联系的位置找到它。松露孢子扩散是通过吃真菌的动物来完成扩散。

松露有一种特殊的香气，自古便有许多人为之着迷。

1825年时法国著名美食家布里亚-萨瓦兰（Jean Anthelme Brillat-Savarin）在其著作《味觉生理学》（Physiologie du Goût）中便盛赞松露为「厨房的钻石」。欧洲人将松露与鱼子酱、鹅肝并列「世界三大珍馐」，属于高贵食材之一，特别是法国产的黑松露（Tuber melanosporum Vitt.）与意大利产的白松露（Tuber magnatum Pico）评价最高。

A truffle is the fruiting body of a subterranean Ascomycete fungus, predominantly one of the many species of the genus Tuber. Some of the truffle species are highly prized as food. French gourmet Jean Anthelme Brillat-Savarin called truffles "the diamond of the kitchen". Edible truffles are held in high esteem in French, Georgian, Greek, Italian, Croatian, Middle Eastern and Spanish cooking, as well as in international haute cuisine. Truffles are ectomycorrhizal fungi and are therefore usually found in close association with the roots of trees. Spore dispersal is accomplished through fungivores, animals that eat fungi.
