Ashikaga Yoshizumi (足利 義澄?, January 15, 1481 – September 6, 1511) was the 11th shogun of the Ashikaga shogunate who reigned from 1494 to 1508 during the Muromachi period of Japan. He was the son of Ashikaga Masatomo and grandson of the sixth shogun Ashikaga Yoshinori. Yoshizumi was first called Yoshitō (sometimes translated as Yoshimichi), then Yoshitaka.
Yoshizumi was adopted by the 8th shogun Ashikaga Yoshimasa. He was installed by Hosokawa Masamoto as Seii Taishogun. He was stripped of the title in 1508 by the 10th shogun Ashikaga Yoshitane, who became shogun for a second period of time.
