附果（英语：Accessory fruit，或称为假果）指不是只由子房发育而成，而是由花萼、花冠，甚至是整个花体序参与发育而成的果实，其结构比正常果实复杂得多。

相对于附果，一般的果实是花粉通过各种途径传播到雌花柱头上，这是传粉。花粉通过萌发花粉管深入子房胚囊让其受精。受精后通过一系列的发育，最终受精卵发育成种子，而子房发育成包裹种子的果实。

An accessory fruit (sometimes called false fruit, spurious fruit, pseudofruit, or pseudocarp) is a fruit in which some of the flesh is derived not from the ovary but from some adjacent tissue exterior to the carpel. Examples of accessory tissue are the receptacle of the strawberry, pineapple, common fig, and mulberry, and the calyx of Gaultheria procumbens or Syzygium jambos. Pomes, such as apples and pears, are also accessory fruits, with much of the fruit flesh derived from a hypanthium. Other example could be the anthocarps specific to the family Nyctaginaceae, where most of the fruit comes from the perianth (floral whorls).
