Shizuka Gozen (静御前) (1165–1211), or Lady Shizuka, one of the most famous women in Japanese history and literature, was a shirabyōshi of the 12th century, and a mistress of Minamoto no Yoshitsune. Since she, like many others, are featured largely in the Heike Monogatari, Gikeiki, and a number of plays of various traditions, her story is quite well known, but it is difficult to separate fact from fiction within it.

Minamoto no Yoshitsune was a commander of the Minamoto clan of Japan in the late Heian and early Kamakura periods. During the Genpei War, he led a series of battles that toppled the Ise-Heishi branch of the Taira clan, helping his half-brother Yoritomo consolidate power. He is considered one of the greatest and the most popular warriors of his era, and one of the most famous samurai in the history of Japan. Yoshitsune perished after being betrayed by the son of a trusted ally.
