Ono no Komachi (834?-?) served at the Japanese imperial court in the capital city of Heiankyo (present-day Kyoto) in the early Heian era. Very little is known about her but she was a legendary beauty.

She became the central character of many Japanese legends, including 15 plays of Noh drama and apparently a Chinese opera as well. There is also a modern Noh drama written by Tsumura Kimiko (1902-1974) called "Fumigara" (The Love Letters) featuring Ono no Komachi.
