Asano Tsunanaga (浅野 綱長, July 28, 1659 – April 1, 1708) was a Japanese daimyō of the Edo period, who ruled the Hiroshima Domain.
His childhood name was Iwamatsu (岩松).
During the 47 rōnin incident, Tsunanaga sent a messenger to Akō, which was ruled by a branch family of the Hiroshima Asano, and recommended that Ōishi Kuranosuke peacefully surrender the castle to the shogunate's envoys.
His daughter married the court noble Ichijō Kaneka.
