哈伦·拉希德（阿拉伯语：هارون الرشيد‎；英语：Harun al-Rashid，763年－809年3月24日）是阿拔斯王朝的第五代哈里发。他是阿拔斯王朝第三任哈里发阿尔·马赫迪之子，在786年继其兄阿尔·哈迪之位，任期间为王朝最强盛时代，曾亲率军队入侵拜占廷的小亚细亚。其首都巴格达和唐朝长安为世界第一流的城市，人口多达100万，也是国际贸易中心。不过哈伦时代也是王朝衰退的开端。西元803年哈伦逮捕宰相约夫雅，巴尔马克家族被抄家，导致波斯发生叛变。哈伦也死于波斯的托斯，至此阿拔斯王朝步入衰退之路。

Harun al-Rashid (/hɑːˈruːnɑːlrɑːˈʃiːd/ Arabic:هَارُون الرَشِيد‎, Hārūn Ar-Rašīd; 17 March 763 or February 766 — 24 March 809 (148-193 Hijri) was the fifth Abbasid Caliph. His birth date is debated, with various sources giving dates from 763 to 766. His surname translates to "the Just", "the Upright", or "the Rightly-Guided"; fully translated, his name means "Aaron the Just". Al-Rashid ruled from 786 to 809, during the peak of the Islamic Golden Age. His time was marked by scientific, cultural, and religious prosperity. Islamic art and music also flourished significantly during his reign. He 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 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. In 796, he moved his court and government to Ar-Raqqah in present-day Syria.
