Asano Yoshinaga (浅野 幸長, 1576 – October 9, 1613) was a Japanese samurai and feudal lord of the late Sengoku and early Edo periods. His father served as one of the Go-Bugyō in the late Azuchi–Momoyama period. Asano Yoshinaga was born at Odani, in the Asai district of Ōmi Province, in 1576, the eldest son of Asano Nagamasa, the brother of O-Ne, Toyotomi Hideyoshi's wife. He married a daughter of Ikeda Tsuneoki. Yoshinaga achieved distinction together with his father in 1597, during the Siege of Ulsan, when they held the fortress under the command of Katō Kiyomasa.
