Satake Yoshishige (佐竹 義重, March 7, 1547 – May 19, 1612) was a Japanese daimyō (military lord) of the Sengoku period.

[1] An aggressive lord, Yoshishige consolidated the Satake's hold over Hitachi and fought with such local houses as the Ashina, Oda, and Naya.

Yoshishige organized his followers and henchmen into four groups: ichimon, fudai, tozama, and kakushō-shu.

Yoshishige resisted Hôjô expansion into the eastern Kanto region for many years, who were extending their power into southern Hitachi.

Yoshishige handed official control of the Satake to his son Yoshinobu in 1589 but remained effectively in command afterwards.

In the aftermath of the Battle of Sekigahara, Yoshishige was able to intercede on behalf of Yoshinobu when the latter was set to be punished by Tokugawa Ieyasu for his indecisive behavior.
