Satake Yoshiharu (佐竹義明, December 2, 1723 – April 25, 1758) was the 7th daimyō of Kubota Domain in Dewa Province, Japan (modern-day Akita Prefecture), and then 25th hereditary chieftain of the Satake clan.

Kubota Domain continued to be rent by peasant uprisings and by plots among his retainers caused by the years of mismanagement of the domain by his predecessors, complicated by a very severe crop failure in 1754.

Yoshiharu attempted to reign in the economic situation by issuing hansatsu paper money with a face value in silver.

People who had the paper currency found it to be worthless, and this in turn led to the "Akita riot" of 1757, a large-scale uprising against the government.

Yoshiharu died the following year at Kubota Castle at the suspiciously young age of 36.
