仙女虫科（Naididae），以往称为颤蚓科，是环带纲的环节动物，其下包括有正颤蚓。牠们是淡水及海洋底栖带生态系统的重要成员。

18S核糖体DNA的分析发现仙女虫科可能不是一个单系群。最坏的情况是将仙女虫亚科与其他科组合成并系群，但这却涉及修改科名。

仙女虫科可以分为6个亚科，按其系统发生次序：

The Naididae (formerly known as Tubificidae) are a family of clitellate oligochaete worms like the sludge worm, Tubifex tubifex. They are key components of the benthic communities of many freshwater and marine ecosystems. In freshwater aquaria they may be referred to as detritus worms.
