The Imo Incident, also referred to as the Imo Mutiny, was a military revolt by some units of the Korean military in Seoul, on July 23, 1882. The initial cause for the violence was due to dissatisfaction with the Korean government, and worries about Japanese military advisors and the support Emperor Gojong was showing them.

Initially, government officials were attacked and killed by the rioters, who were swelled by Seoul's general population. The regent father of the emperor, the Heungseon Daewongun, took power during the chaos and supported the rioting soldiers.

A number of Japanese were killed during the rioting, and ultimately led to Chinese troops being deployed to quell the rebellion, arresting the Daewongun. The Japanese government also sent four naval ships and a battalion of armed soldiers.
