The siege of Toyama was a battle during the Azuchi-Momoyama period (16th century) of Japan.

During the late summer of August 1585, Toyotomi Hideyoshi had led his army of around 100,000 soldiers against Sassa Narimasa, a once former ally many years past.

During the siege of Toyama, Toyotomi's senior commander Maeda Toshinaga would play a very prominent role within the overall attack.

In the end, Narimasa's defence was shattered, thus allowing Toyotomi supremacy over Etchu province.
