Classical Arabic or Quranic Arabic (Arabic: العربية الفصحى, romanized: al-ʻArabīyah al-Fuṣḥā, lit. 'the most eloquent classic Arabic') is the standardized literary form of Arabic used from the 7th century and throughout the Middle Ages, most notably in Umayyad and Abbasid literary texts such as poetry, elevated prose and oratory, and is also the liturgical language of Islam. Classical Arabic is, furthermore, the register of the Arabic language on which Modern Standard Arabic is based.

Several written grammars of Classical Arabic were published with the exegesis of Arabic grammar being at times based on the existing texts and the works of previous texts, in addition to various early sources considered to be of most venerated genesis of Arabic. The primary focus of such works was to facilitate different linguistic aspects.

Modern Standard Arabic is its direct descendant used today throughout the Arab world in writing and in formal speaking, for example prepared speeches, some radio and television broadcasts and non-entertainment content. The lexis and stylistics of Modern Standard Arabic are different from Classical Arabic, and Modern Standard Arabic uses a subset of the syntactic structures available in Classical Arabic, but the morphology and syntax have remained basically unchanged. In the Arab world little distinction is made between Classical Arabic and Modern Standard Arabic and both are normally called al-fuṣḥā (الفصحى) in Arabic, meaning 'the most eloquent'.
