Kamachi Akimori (蒲池 鑑盛, 1520 - December 7, 1578) was a Japanese retainer of the Ōtomo clan during the Sengoku period.
He served under Ōtomo Sōrin.
He was known as a skilled commander in the battle and also considered to be one of the pillars for the Otomo house serving in all their major campaigns.
On 1578, Otomo Yoshishige attacked the Shimazu clan and Yamada Arinobu gathered 500 troops to hold ground at Taka Castle. He managed to defend the castle and this led to a decline in the morale of the Otomo troops. In the Battle of Mimigawa that followed, the Shimazu army defeated Otomo, who retreated under heavy losses. Kamachi Akimori died in the battle.
