Ki no Tsurayuki (紀 貫之?, 872 – June 30, 945) was a Japanese author, poet and courtier of the Heian period. He is best known as the principle compiler of the Kokin Wakashū and as the author of the Tosa Diary (although the latter was published anonymously).
Tsurayuki was a son of Ki no Mochiyuki. He became a waka poet in the 890s. In 905, under the order of Emperor Daigo, he was one of four poets selected to compile the Kokin Wakashū, the first imperially-sponsored anthology (chokusen-shū) of waka poetry.
After holding a few offices in Kyoto, he was appointed the provincial governor of Tosa province and stayed there from 930 until 935. Later he was presumably appointed the provincial governor of Suo province, since it was recorded that he held a waka party (Utaai) at his home in Suo.
He is well known for his waka and is counted as one of the Thirty-six Poetry Immortals selected by Fujiwara no Kintō. He was also known as one of the editors of the Kokin Wakashū. Tsurayuki wrote one of two prefaces to Kokin Wakashū; the other is in Chinese. His preface was the first critical essay on waka. 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.
His waka is included in one of the important Japanese poetry anthologies, the Hyakunin Isshu, which was compiled in the 13th century by Fujiwara no Teika, long after Tsurayuki's death.
