卷尾科（学名Dicruridae）是鸟纲雀形目的一个科。这一科的鸟是一类中等体型的雀类，体羽多灰色或黑色，有些种类的外侧尾羽向外向上弯曲，因此而的名。

卷尾科下有两个属：

The drongos, subfamily Dicrurinae, are a subfamily of small passerine birds of the Old World tropics in the family Dicruridae. Originally the family included the single genus Dicrurus (subfamily Dicrurinae), but now it has been expanded to include the subfamilies Rhipidurinae (Australasian fantails), Monarchinae (monarchs and paradise flycatchers) and Grallininae (magpie-larks). The subfamily Dicrurinae contains two genera, the monotypic Chaetorhynchus, and Dicrurus, which contains about 25 species. The placement of the pygmy drongo (Chaetorhynchus papuensis) in the subfamily is in dispute on morphological and genetic grounds.
