Abu Bakr Muhammad (died 941) was the first Muhtajid ruler of Chaghaniyan (until 939) and governor of Samanid Khurasan (933–939).
They may have been descended from the Chaghan Khudahs, who ruled Chaghaniyan during the early Middle Ages.
When in 929 the Samanid amir Nasr II was temporarily expelled from power by his brothers, Muhammad remained loyal to him.
As a result, when Nasr managed to regained power, he rewarded Muhammad with the governorship of Balkh, and then in 933 made him governor of Khurasan.
During his time as governor of Khurasan, Muhammad battled various Dailamite bands in northern Iran.
