Adachi Kagemori (安達 景盛) (? - 1248) was a warrior of the Adachi family and was a son of Morinaga. He served with Minamoto no Yoriie but became a monk when Minamoto no Sanetomo died. This did not stop him from joining the Hojo Family for the Jokyu incident, however.
Hojo Tsunetoki and Hojo Tokiyori were his grandsons.
