Abū Jaʿfar Hārūn ibn Muḥammad ar-Rashīd, or simply Hārūn ibn al-Mahdī (763 or 766 – 24 March 809), famously known as Hārūn al-Rashīd, was the fifth Abbasid caliph of the Abbasid Caliphate, reigning from September 786 until his death in March 809. His reign is traditionally regarded to be the beginning of the Islamic Golden Age. His epithet al-Rashid translates to "the Just", "the Upright", or "the Rightly-Guided".

Harun established the legendary library Bayt al-Hikma ("House of Wisdom") in Baghdad in present-day Iraq, and during his rule Baghdad began to flourish as a world center of knowledge, culture and trade. During his rule, the family of Barmakids, which played a deciding role in establishing the Abbasid Caliphate, declined gradually.
