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.
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.
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.
Though the Asano family was secure following its service under Tokugawa Ieyasu at the Battle of Sekigahara, it would be moved to Wakayama Domain, in Kii Province.
Yoshinaga's three-dimensional battle standard, a gold-plated basketlike object, was well known during the Korean campaign.
