Nijō Taikō Taigōgū no Daini (二条太皇太后宮大弐, dates unknown) was a Japanese noblewoman and waka poet of the Heian period.
She was a daughter of Fujiwara no Michimune (藤原通宗, 1040?–1084) and a granddaughter of Dazai no Daini Tsunehira [ja].
She is often confused with Daini no Sanmi, as well as the similarly nicknamed wet nurse of Emperor Horikawa.
She also left a personal anthology, Nijō Taikō Taigōgū no Daini Shū (二条太皇太后宮大弐集).
[1] She lost her father in 1084,[2] but she was supported by her grandfather Tsunehira and her uncle Michitoshi [ja],[2] and collaborated in the compilation of the Goshūi Wakashū.
