齿龈音（舌尖中音）是舌尖音的一种、亦称尖音。发音时，舌尖住上顶齿龈。

英语的/t/，/d/塞音是齿龈塞音，但法语、俄语等语言的舌尖塞音会是齿音。

得到IPA确认的齿龈音如下：

Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli (the sockets) of the superior teeth. Alveolar consonants may be articulated with the tip of the tongue (so-called apical consonants), as in English, or with the flat of the tongue just above the tip (the "blade" of the tongue; called laminal consonants), as in French and Spanish. The laminal alveolar articulation is often mistakenly called dental, because the tip of the tongue can be seen near to or touching the teeth. However, it is the rearmost point of contact that defines the place of articulation; this is where the oral cavity ends, and it is the resonant space of the oral cavity that gives consonants and vowels their characteristic timbre.
