Andō Chikasue (安東 愛季; 1539 – October 2, 1587) was a Japanese daimyō of the Sengoku period, who was a powerful figure in the north half of Dewa Province. Chikasue was the son of Andō Kiyosue.

Chikasue united the Hiyama Ando and Minato Ando families who had been divided. He obtained some mines, and he ruled the Akita port directly. He changed the name of the clan from Andō to Akita and was extolled as being like the Big Dipper in the northern sky. However, he died of sickness immediately before the unification of the north half of Dewa Province.

He was succeeded by his son Akita Sanesue.
