角果是果实的一种类型，属于单果，是十字花科植物特有的果实类型，一些角果被人类当作中药食用一些则用来榨油或者调味料，如油菜、白芥等。

根据角果的形状，角果可以分为

角果由两心皮合生雌蕊发育而成。在果实两侧心皮合生的部位形成两条腹缝线，发育过程中腹缝线之间会形成隔膜将果实分为两个格室，这个隔膜并非由胎座发育而成，因而被称谓假隔膜，果实成熟后会果皮沿腹缝线开裂脱落，种子随之散布，而假隔膜则一直存流于果柄之上。

A silique or siliqua (plural siliques or siliquae) is a fruit (seed capsule) of 2 fused carpels with the length being more than three times the width. When the length is less than three times the width of the dried fruit it is referred to as a silicle. The outer walls of the ovary (the valves) usually separate when ripe, leaving a persistent partition (the replum). This classification includes many members of the Brassicaceae family, but some species have a shorter fruit of similar structure, in which case the fruit is called silicle. Some species that are closely related to plants with true siliques have fruits with a similar structure that do not open when ripe; these are usually called indehiscent siliques (compare dehiscence).
