Sanada Saemon-no-Suke Yukimura (真田 左衛門佐 幸村, Sanada Yukimura?, 1567 – June 3, 1615 (Keichō 20. 5.7)) was a Japanese samurai, second son of the Sengoku period daimyo Sanada Masayuki (1544–1611). His proper name was Sanada Nobushige (真田 信繁), named after Takeda Shingen's younger brother Takeda Nobushige, who was a brave and respected warrior. He and his father were known as excellent military tacticians. Though their army was very small, they won many battles in which they were outnumbered. Sanada Yukimura was called "A Hero who may appear once in a hundred years" and "Crimson Demon of War", and the famed veteran of the invasion of Korea, Shimazu Tadatsune, called him the "Number one warrior in Japan" (日本一の兵?).
