Japanese actor, playwright, and musician who was one of the founders of nō (Noh theatre) drama.

Kan'ami organized a theatre group in Obata to perform sarugaku (a form of popular drama that had at one time included tricks, acrobatics, and slapstick skits), which by his time were plays with dialogue, acrobatics, and dances. He moved his troupe to Yamato and formed the Yūzaki Theatrical Company, which eventually became the highly influential Kanze school of nō. His popularity spread, and he began traveling to Kyōto to perform there as well. At one such performance in 1374 the shogun Ashikaga Yoshimitsu was in the audience and was so favourably impressed that he became Kan'ami's patron and thus enabled Kan'ami to continue refining the form and to write new plays.

Kan'ami was the first to incorporate kusemai (a popular song and dance form with a strong irregular beat) in the drama. He also used music and dances of the dengaku (rustic harvest celebrations). Thus he brought together the two principal tributaries to nō in his plays, which also set new standards of literary quality for drama. Some of the outstanding works attributed to him are Komachi, Ji'nen koji, Shii no shōshō, Matzukaze, and Eguchi. His son Zeami Motokiyo, trained by Kan'ami in the theatrical arts, acted, wrote plays, and became the foremost theorist of the nō theatre. He succeeded his father as director of the Kanze school.
