The 1590 siege of Oshi was one of many battles in Toyotomi Hideyoshi's campaigns against the Hōjō clan during Japan's Sengoku period.

Oshi, which was a castle under the control of the Hōjō clan, was attacked by senior Toyotomi retainer Ishida Mitsunari. Throughout this siege, Mitsunari used a prior strategy of Toyotomi Hideyoshi, that of diverting a river to flood the whole castle area. Yet, the defenders under the Hojo retainers Narita clan held out until the fall of the Hojo stronghold Odawara.
