Abu'l Hassan Ali ibn Ridwan Al-Misri (Arabic: أبو الحسن علي بن رضوان المصري) (c. 988 - c. 1061) was an Arab[1] of Egyptian origin who was a physician, astrologer and astronomer, born in Giza.

He was a commentator on ancient Greek medicine, and in particular on Galen; his commentary on Galen's Ars Parva was translated by Gerardo Cremonese. However, he is better known for providing the most detailed description of the supernova now known as SN 1006, the brightest stellar event in recorded history, which he observed in the year 1006.[2] This was written in a commentary on Ptolemy's work Tetrabiblos.

He was later cited by European authors as Haly, or Haly Abenrudian. According to Alistair Cameron Crombie[3] he also contributed to the theory of induction. He engaged in a celebrated polemic against another physician, Ibn Butlan of Baghdad.[4]

He died in Egypt in 1061.[6]
