Ashikaga Yoshiteru , also known as Yoshifushi or Yoshifuji, was the 13th shōgun of the Ashikaga shogunate who reigned from 1546 to 1565 during the late Muromachi period of Japan. He was the eldest son of the 12th shōgun, Ashikaga Yoshiharu, and his mother was a daughter of Konoe Hisamichi. When he became shogun in 1546 at age 11, Yoshiteru's name was Yoshifushi ; but some years later in 1554, he changed his name to the one by which he is conventionally known today. His childhood name was Kikubemaru (菊童丸). His younger brother Ashikaga Yoshiaki became the fifteenth shōgun.

Shogun, officially sei-i taishōgun , was the title of the military rulers of Japan during most of the period spanning from 1185 to 1868. Nominally appointed by the Emperor, shoguns were usually the de facto rulers of the country. Although during part of the Kamakura period and Sengoku period, shoguns were figureheads themselves, with real power in the hands of the shikken (執権) of the Hōjō clan and kanrei (管領) of the Hosokawa clan. In addition, Taira no Kiyomori and Toyotomi Hideyoshi were leaders of the warrior class who did not hold the position of shogun, the highest office of the warrior class, yet gained the positions of daijō-daijin and kampaku , the highest offices of the aristocratic class. As such, they ran their governments as its de facto rulers.
