The Avestan alphabet (Middle Persian: transliteration: dyn' dpywryh, transcription: dēn dēbīrē, Persian: دین دبیره, romanized: din dabire) is a writing system developed during Iran's Sasanian era (226–651 CE) to render the Avestan language.

As a side effect of its development, the script was also used for Pazend, a method of writing Middle Persian that was used primarily for the Zend commentaries on the texts of the Avesta. In the texts of Zoroastrian tradition, the alphabet is referred to as "the religion's script" (dēn dibīrih in Middle Persian and din dabireh in New Persian).
