世阿弥（1363年－1443年9月1日），日本室町时代初期的猿楽演员与剧作家。

与其父观阿弥共同为集猿楽（或作申楽，现在的能）之大成者，留下了许多著作。观阿弥、世阿弥的能剧由观世流继承至今。

幼名鬼夜叉，后由二条良基赐名藤若。通称三郎。本名为元清。其父死后，世阿弥继承了观世大夫的名号。自40多岁起取艺名世阿弥，意为世阿弥陀佛。

世阿弥的作品中有将近50曲仍在现代的能剧中上演。他所作的艺术批论书例如『风姿花传』等等，除了是重要史料之外，也具有很高的文学价值。

Zeami Motokiyo(世阿弥 元清) (c. 1363 – c. 1443), also called Kanze Motokiyo(観世 元清), was a Japanese aesthetician, actor, and playwright. His father, Kan'ami, introduced him to Noh theater performance at a young age, and found that he was a skilled actor. Kan'ami was also skilled in acting and formed a family theater ensemble. As it grew in popularity, Zeami had the opportunity to perform in front of the Shogun, Ashikaga Yoshimitsu. The Shogun was impressed by the young actor and began to compose a friendship with him. Zeami was introduced to Yoshimitsu's court and was provided with an education in classical literature and philosophy while continuing to act. In 1374, Zeami received patronage and made acting his career. After the death of his father in 1385, he led the family troupe, a role in which he found greater success.
