Daini no Sanmi (大弐三位, dates unknown[1] but born c. 999[2]) was a Japanese waka poet of the mid-Heian period.

[4] In 1017, she joined to the court and served as a lady-in-waiting for Grand Empress Dowager Shoshi, the mother of Emperor Go-Ichijo.

Thirty-seven[2] or thirty-eight[non-primary source needed] of her poems were included in imperial anthologies from the Goshūi Wakashū onward.

One of her poems was included as the fifty-eighth in the Ogura Hyakunin Isshu: 有馬山猪名の笹原風吹けば     いでそよ人を忘れやはする Arima-yama ina no sasahara kaze fukebaide soyo hito o wasure ya wa suru[5]At the foot of Mt.

[1][2] Some scholars have attributed the final ten chapters of her mother's magnum opus, The Tale of Genji, to her.
