Al-Kāfī (Arabic: الکافی) is one of the most important and authentic Twelver Shi'a hadith collections, and the first of the the Four Books. It was compiled by Thiqat al-Islam al-Kulayni (d. 329/941) in the Minor Occultation period.

Al-Kulayni states in his introduction that he has collected hadith in such a way that they agree with the consensus and there is no incompatibility between them and the Qur'an. Furthermore, when he saw no preference between two incompatible hadiths, he chose the one he deemed more correct and authentic.
