The Sambyeolcho Rebellion (1270–1273) was a Korean rebellion against the Goryeo dynasty that happened at the last stage of the Mongol invasions of Korea. It was suppressed by the Goryeo and the Mongol Yuan dynasty. After the rebellion Goryeo became a vassal of the Yuan dynasty, division of the Mongol Empire.

From 1231, Goryeo was intermittently invaded by the Mongol Empire. During this time, Goryeo was controlled by a military regime led by the Choe family. In 1232 the government under the nominal king fled to Ganghwa Island, which Mongol horse riders were unable to land on, and resisted the Mongol invasion. Unfortunately because of its fragile foundation, Goryeo faced frequent rebellions. The 1258 rebellion resulted in the establishment of Ssangseong (쌍성총관부, 雙城摠管府) and Dongnyeong Prefectures (동녕부, 東寧府) by the Mongols.

Unlike these rebels, the Sambyeolcho (Three Elite Patrols) were an organ of the military government. They were organized by the Choe family to maintain security. However, unlike the Choe private guards unit (which was to personally protect the family), the Sambyeolcho assumed public functions performed by police and combat forces, effectively replacing the Six Divisions of the military.

In 1258, Choe Ui, the fourth of the Choe family, was overthrown by Kim Jun (also known as Kim Injun) using the Sambyeolcho. Kim Jun took a pro-Mongol policy and sent Crown Prince Wang Jeon to the Mongol Empire. At the same time, King Gojong and the crown prince approached the Mongols to restore power from Kim Jun.

In 1268, however, Kim Jun was annihilated by the Sambyeolcho under the order of Im Yeon. The next year, Im Yeon's attempt to replace King Wonjong was reversed by the crown prince (Chungnyeol) with the help from the Mongol force. In 1270, Im Yeon's successor Im Yumu was killed by the pro-Mongol faction using the Sambyeolcho. It marked the end of the military regime.
