'Abd al-Rahman ibn 'Umar Zain al-Din al-Dimashqi, commonly known as Al-Jawbari (Arabic: الجوبري‎‎; fl. 619/1222[1]) was an Arab author known for his writings that denounce alchemical imposture and superstitions.[2]

Al-Jawbari wrote the "Book of Selected Disclosure of Secrets" (Kitāb al-mukhtār fī kashf al-asrār) exposing the fraudulent and deceptive antics which he had seen practiced by the wandering quacks, the charlatans, fake alchemists and money changers.[3] In it he speaks of "the people of al-kimya (alchemists) who know three hundred ways of making dupes". The book also describes the preparation of rose water.[4]

He was born in Jawbar.
