卵生动物（Ovipara）是指在有性生殖中，母体的卵受精后形成新个体的动物。新个体从母体排放出来后，以卵内的蛋白质提供营养，继续发育待完成。最后，新个体破卵而出。爬行类、两生类、鸟类及哺乳类中的单孔目大多为卵生动物。

Oviparity 卵生动物
（重定向自Oviparous reproduction）
Oviparous animals are animals that lay eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, reptiles, all birds, and the monotremes.
In traditional usage, most insects, molluscs, and arachnids are also described as oviparous; Thierry Lodé (2012), however, describes the mode of reproduction in these organisms as "ovuliparous".
