足利义满（1358年9月25日－1408年5月31日），大明日本国王（1401年1394年在任），室町幕府第三任将军（1368年至1394年在任）。他是第二代将军足利义诠的儿子，母亲是义诠的侧室纪良子。

足利义满在任期间，南北朝获得统一。足利义满对势力较为强大的守护大名进行了压制，改革政制，设“三管四职”，确立了幕府的中央集权。同时创建了金阁寺（鹿苑寺），是为室町时代北山文化的代表作。其在任时期是室町时代政治、经济和文化最为强盛的时期。

1378年，足利义满将邸宅迁往了京都的北小路室町，在那里创建了花之御所。因此义满被人称作室町殿。历史用语室町幕府就是由此得名。

Ashikaga Yoshimitsu(足利 义満, September 25, 1358 – May 31, 1408) was the 3rd shogun of the Ashikaga shogunate, which was in power from 1368 to 1394 during the Muromachi period of Japan. Yoshimitsu was appointed shogun, hereditary head of the military estate, in 1368 at the age of ten; at twenty he was admitted to the imperial court as Acting Grand Counselor (Gon Dainagon 権大纳言). In 1379, Yoshimitsu reorganized the institutional framework of the Gozan Zen 五山禅 establishment before, two years later, becoming the first person of warrior pedigree to host a reigning emperor at his private residence. In 1392, he negotiated the end of the Nanbokuchō imperial schism that had plagued politics for over half a century. Two years later he became Grand Chancellor of State (Dajō daijin 太政大臣), the highest-ranking member of the imperial court. Retiring from that and all public offices 1395, Yoshimitsu took the tonsure and moved into his Kitayama-dono (北山殿) retirement villa which, among other things, boasted a pavilion covered in gold leaf (Kinkaku shariden 金阁舎利殿). There, he received envoys from the Ming and Chosŏn courts on at least six occasions and forged the terms of a Sino-Japanese trade agreement that endured for over a century. In recognition for his diplomatic efforts (and overt displays of subservience), the Chinese sovereign pronounced Yoshimitsu "King of Japan" (Nihon kokuō 日本国王). In 1407, he set into motion a plan to become "Dajō tenno" (太上天皇), a title customarily applied to a retired emperor. Although unrealized due to his sudden death the following year, this last venture was particularly audacious because Yoshimitsu never actually sat on the Japanese throne.
