营养繁殖是植物无性繁殖的方法之一。是由根、茎、叶等营养器官形成新个体的一种繁殖方式；植物各个营养器官均有一定的再生能力，如枝条能长出不定根，根上能产生不定芽等，从而长成整体。

在这个过程中，新的个体植物无需种子或孢子产生；人工的营养繁殖包括扦插、压条等方法繁殖（如马铃薯、草莓、桑树、柳树等），其好处是不需等候种子发育等过程，需时较短。

苔藓、蕨类和低等植物以营养体断裂的方式进行营养繁殖也很普遍。

自然的营养繁殖是植物求生的一种方法。有些植物在气候良好时积累食物，保存在营养繁殖的器官中。这类器官通常是变异的根或茎。当环境不宜，原先的植物死去。当气候转好，营养繁殖的器官便会生出枝叶，继续生长。
