Mikhail Grigoroevich Akimov (1847–1915) was a Russian politician.

After graduating from the University of Moscow, he entered the Ministry of Justice.

He served as an Assistant Public Prosecutor in Kiev in 1881.

It is known that he was on the roster of Senators in December 1905, because the Chairman of the Council of Ministers, Sergei Witte, chose him to be the successor of Sergey Manukhin from that list.

He was eventually chosen as the Chairman of the Imperial State Council.
