果实，是被子植物（也称显花植物）花的部份组织衍生成的生殖器官，通常在开花授粉之后，以受精的子房为主体而形成，其中包含有种子。植物借由果实来传播种子。其中有许多是可以食用的，人类或动物食用果实后移动，有助于种子传播，而果实可以提供人类或动物营养，两者之间有共生关系，而果实也是人类及许多动物的食物来源之一。世界上的农业产品中，果实占了其中很大的一部份。

水果是指可以生食，多汁液，有酸味或甜味的果实，像苹果、橙、葡萄、香蕉及柠檬等。但在植物学的定义上，也有一些不被视水果的果实，例如豆子、玉米粒、小麦的麦穗及番茄。

In botany, a fruit is the seed-bearing structure in flowering plants (also known as angiosperms) formed from the ovary after flowering.

Fruits are the means by which angiosperms disseminate seeds. Edible fruits, in particular, have propagated with the movements of humans and animals in a symbiotic relationship as a means for seed dispersal and nutrition; in fact, humans and many animals have become dependent on fruits as a source of food. Accordingly, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings.
