Ki no Tsurayuki (紀 貫之, 872 – June 30, 945) was a Japanese author, poet and court noble of the Heian period.

In 905, under the order of Emperor Daigo, he was one of four poets selected to compile the Kokin Wakashū (Kokinshu), the first imperially-sponsored anthology (chokusen-shū) of waka poetry.

He wrote of its history from its mythological origin to his contemporary waka, which he grouped into genres, referred to some major poets and gave a bit of harsh criticism to his predecessors like Ariwara no Narihira.

The female perspective of the diary, though written by a man (Tsurayuki), has sparked debate among scholars regarding gender and social status within the realm of linguistics of the time period.
