Apology of al-Kindi (also spelled al-Kindy) is a medieval theological polemic making a case for Christianity and drawing attention to alleged flaws in Islam. The word "apology" is a translation of the Arabic word ‏رسالة‎, and it is used in the sense of apologetics. It is attributed to an Arab Christian referred to as Abd al-Masih ibn Ishaq al-Kindi. This Al-Kindi is otherwise unknown, and is clearly different from the Muslim philosopher Abu Yûsuf ibn Ishâq al-Kindī.The significance of the work lies in its availability to Europe's educated elite from as early as the twelfth century as a source of information about Islam.
