Ḥarbī al-Ḥimyarī () is a semi-legendary Himyarite sage that occurs several times in the writings attributed to the Islamic alchemist Jābir ibn Ḥayyān (died c. 806−816). He is said there to have been one of Jabirs teachers, and to have been 463 years old when Jabir met him. One of Jabirs lost works was dedicated to Harbi al-Himyaris contributions to alchemy, a fact which may point to the existence in Jabirs time of a written work attributed to him.
