Abu Bakr Muhammad ibn Ra'iq (Arabic: محمد بن رائق‎‎) (died 13 February 942), usually simply Ibn Ra'iq, was a senior official of the Abbasid Caliphate, who exploited the caliphal government's weakness to become the first amir al-umara ("commander of commanders", de facto regent) of the Caliphate in 936. Deposed by Turkish military leaders in 938, he regained the post in 941 and kept it until his assassination in February 942.
