Abu Bakr Muhammad ibn Ra'iq (died 13 February 942), usually simply known as 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", generalissimo and de facto regent) of the Caliphate in 936. Deposed by rival Turkish military leaders in 938, he regained the post in 941 and kept it until his assassination in February 942.
