Ii Naotora (井伊 直虎, d. 12 September 1582) was a daimyō of the Sengoku period. She was the daughter and only child of Ii Naomori, the eighteenth head of their clan. She was primarily the head of Ii clan and retainer of the Imagawa clan, because of her efforts, Ii Naotora becomes a daimyō and received the title "Female Landlord" (女地頭).
Ii Naotora was a daughter of Ii Naomori, a leader of Iinoya-is a part of Tōtōmi, who had been defeated by Imagawa Yoshimoto and became a vassal of Imagawa. The Ii family had no male heir, so Natora's uncle Ii Naomitsu tried to betrothe Ii Naochika his son to her so that he could inherit the clan. However, Naomitsu planned to rebel against Imagawa. Unidentified Imagawa clan retainers carried a report of the plans to Imagawa, who ordered Naomitsu and his son Naochika to commit seppuku. Naomitsu died, but Naochika, who was very young, was protected by a buddhist priest named Nankei. Naochika managed to flee to Shinano. He returned to Iinoya about ten years later, but he had already married another woman while in exile. Naotora became a priestess, and was named Jiro Houshi by Nankei.
Naochika momentarily ruled the clan but, like his father, he planned a rebellion against Imagawa. Again, anonymous traitors carried news of the plans to Imagawa and Naochika was killed by Imagawa Ujizane in 1560. It is said that he was killed because of an anonymous report of Ono Michiyoshi. Following his death and many obstacles, Naotora returned to secular life and became the nominal head of the clan. She fought in various battles alongside the Tokugawa clan. Naochika's son, the famed Ii Naomasa whom she adopted, succeeded her after her demise in 1582.
