Sei Shōnagon (清少納言^?, lesser councilor of state Sei), (c. 966–1017/1025) was a Japanese author, poet and a court lady who served the Empress Teishi (Sadako) around the year 1000 during the middle Heian period. She is the author of The Pillow Book (枕草子, makura no sōshi^?).

Sei Shōnagon's actual given name is not known. It was the custom among aristocrats in those days to call a court lady by a nickname taken from a court office belonging to her father or husband.Sei (清^?) derives from her father's family name "Kiyohara" (the native Japanese reading of the first character is kiyo, while the Sino-Japanese reading is sei), while Shōnagon (少納言^?, "lesser councilor of state") refers to a government post. Her relationship to this post is unknown, though—neither her father nor either of her two husbands held such a post.Bun'ei Tsunoda has suggested that it may have belonged to a third husband, perhaps Fujiwara no Nobuyoshi.
