Rio Kishida (岸田 理生, Kishida Rio; 1946–2003) was a Japanese playwright and director. She wrote several plays about women and the problems they faced in a patriarchal society that run parallel with the second wave of the feminist movement in Japan. Even though she did not strictly identify herself as a feminist, she believed that the system of a male dominated society had to change in order for women to gain equal rights as their male counterpart.
