Lady Nijō (後深草院二条, Go-Fukakusain no Nijō) (1258 – after 1307) was a Japanese noblewoman, poet and author. She was a concubine of Emperor Go-Fukakusa from 1271 to 1283, and later became a Buddhist nun. After years of travelling, around 1304–07 she wrote a memoir, Towazugatari ("An Unasked-For Tale", commonly translated into English as The Confessions of Lady Nijō), the work for which she is known today, and which is also the only substantial source of information on her life.
