Ashikaga Satouji (?? ??, May 6, 1857 - 1921?) was a Japanese samurai of the late Edo period who served as lord of the Kitsuregawa domain (Shimotsuke Province).
A direct descendant of the Ashikaga shoguns, Satouji had 5000 koku income and was a Tokugawa retainer, but had the de facto status of a daimyo of 100,000 koku-level income.
Satouji became a viscount (??, shishaku) in the Meiji era; however, it is unknown when he died.
