The voiceless pharyngeal fricative is a type of consonantal sound, used in some spoken languages.

In the transcription of Arabic, Berber (and other Afro-Asiatic languages) as well as a few other scripts, it is often written ⟨Ḥ⟩, ⟨ḥ⟩.

Features of the voiceless pharyngeal fricative: This sound is the most commonly cited realization of the Semitic letter hēth, which occurs in all dialects of Arabic, Classical Syriac, Western Neo-Aramaic, Central Neo-Aramaic, Ge'ez, Tigre, Tigrinya as well as Biblical, Mishnaic and Mizrahi Hebrew.

It has also been reconstructed as appearing in Ancient Egyptian, a related Afro-Asiatic language.

Assyrian Neo-Aramaic, Ashkenazi Hebrew and most speakers of Modern Hebrew have merged the voiceless pharyngeal fricative with the voiceless velar (or uvular) fricative.
