Pe is the seventeenth letter of the Semitic abjads, including Phoenician Pē Phoenician pe.svg, Hebrew Pē פ, Aramaic Pē Pe0.svg, Syriac Pē ܦ, and Arabic Fāʼ ف (in abjadi order) and also Persian Peʼ پ.

The original sound value is a voiceless bilabial plosive: /p/; it retains this value in most Semitic languages except for Arabic, which having lost /p/ now uses it to render a voiceless labiodental fricative /f/.
