Cho Hwi () was a Korean soldier who originally served Goryeo but defected to the Mongol Empire in 1259. Appointed by the Mongols as the General Superintendent of the Ssangsà Âng Prefecture, created from the former northeastern territory of Goryeo seized by the Mongols, Cho Hwi and his descendants would maintain hereditary rule over the prefecture until its reconquest by Goryeo nearly a century later in 1356.
Cho Hwi was a native of Yongjin-hyà Ân, Goryeo (modern-day Munchon, North Korea). He was the son of Cho Chisu (), the progenitor of the . In January 1259, the Mongols invaded Goryeo's northeastern region of Tongbungmyà Ân. Tongbungmyà Ân military commissioner Sin Chipp'yà Âng () attempted to move civilians who had fled to Chà Âdo () to Chukto (). Chukto was narrower than Chà Âdo and had no wells. In response to Sin's actions, Cho Hwi, along with T'ak Ch'à Âng () led a rebellion, killing Sin Chipp'yà Âng and other Goryeo officials. They then surrendered all Goryeo territory north of Hwaju to the Mongols. On January 9, 1259, the Mongols created Ssangsà Âng Prefecture, appointing Cho as the General Superintendent () and T'ak as a chiliarch.
As the General Superintendent, Cho took a hostile stance against Goryeo. When Goryeo sent Junior Colonel () Kim Kisà Âng () as an envoy to the Mongols, 30 of Cho's men killed the Goryeo envoys at Munju. He aided Mongol forces on an attack against the Goryeo fort of Han'gye () but was repulsed by Special Supervisor of Defense () An Hongmin (). In 1271, Cho helped rebels in the Yangju capture the local magistrate. Cho was succeeded as the General Superintendent of the Ssangsà Âng Prefecture by his son, Cho Yanggi ().
