Ashikaga Yoshikatsu (足利 義勝, March 19, 1434 – August 16, 1443) was the seventh shōgun of the Ashikaga shogunate who reigned from 1442 to 1443 during the Muromachi period of Japan. Yoshikatsu was the son of 6th shōgun Ashikaga Yoshinori with his concubine, Hino Shigeko (1411–1463).^[1] His childhood name was Chiyachamaru (千也茶丸). Hino Tomiko, wife of Ashikaga Yoshimasa, at first was betrothed to Yoshikatsu.

In 1441, Shōgun Yoshinori is murdered at the age of 48 by Akamatsu Mitsusuke and shortly thereafter it is determined that his 8-year-old son, Yoshikatsu will become the new shōgun.^[2] Yoshikatsu is confirmed as shōgun the following year.^[3] On August 16, 1443 Yoshikatsu died at the age of 9. Fond of horse riding, he was fatally injured in a fall from a horse. He had been shogun for only two years. His 8-year-old brother, Yoshinari, was then named shōgun.^[4] Several years after he became shogun, Yoshinari changed his name to Yoshimasa, and he is better known by that name.^[5]

The years in which Yoshikatsu was shōgun are more specifically identified by only one era name or nengō.^[6]
