Cho Ilsin (Korean: 조일신; Hanja: 趙日新; ? – November 12, 1352) was a Goryeo civil official. A close confidant of King Gongmin while the future king was a Yuan hostage in Dadu, Cho became an official of the Goryeo court after Gongmin's return to Goryeo and ascension to the Goryeo throne. His political rivalry with the influential pro-Yuan Ki family, the kin of Yuan Empress Ki culminated in the Cho Ilsin rebellion in 1352. Cho attempted to eliminate the Ki family but failed, and was executed by King Gongmin.
