卷舌音，又称翘舌音、舌尖后音。指辅音的舌尖音中，舌尖和上颚前部接触以形成对气流的阻碍而发出来的音。

由国际音标所确准的卷舌音如下：

A retroflex consonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants, especially in Indology. Other terms occasionally encountered are domal and cacuminal.
