Date Munehiro or Chihiro (Japanese:伊達 宗広 or 千広; June 24, 1802 – May 18, 1877) was a Japanese samurai of Kii Domain and Scholar of Kokugaku, living during the late Edo and early Meiji periods.

In 1852, he was arrested by an opponent for his dangerous Sonnō jōi activity and was imprisoned for nearly 10 years in the town of Tanabe (紀伊 田辺).

In 1861, he was released by the agency of Yamanouchi Yōdō (山内 容堂), who was a daimyō of Tosa Domain (土佐).

He transferred his patrimony to his adoptive son, Date Muneoki (伊達 宗興) and retired.

But when he was imprisoned in Kii Tanabe, he borrowed the Issai-Sūtra (一切経) from a temple in the neighborhood and read it every day.
