Yi Gwal's Rebellion was an armed rebellion in the Joseon dynasty led by General Yi Gwal, who helped Injo ascend to the throne and incited a rebellion against him for being rewarded poorly and trying to arrest his son. He led 12,000 of his soldiers to occupy Hanseong and replace him with Heungangun, his royal relative as king. But the Joseon army led by General Jang Man (张晚) retook the capital and crushed the rebellion, preserving King Injo's rule.

Yi Gwal was subsequently executed by his own army. Yi Gwal's Rebellion weakened the Korean military, making them vulnerable to the Later Jin's invasion.
