Cho In-gyu (Korean: 조인규; Hanja: 趙仁規; 1237 – May 15, 1308[a]) was a Goryeo civil official.
He would eventually become the chancellor of Goryeo by 1292 and marry his daughter to the crown prince, the future King Chungnyeol.
He first was given the rank of senior colonel (중랑장; 中郎將; chungnangjang), for his services in helping arrange the marriage between the heir of Goryeo and Kublai's daughter.
She sent messages to the Yuan court, accusing her rival of having placed a curse on her causing the king to not love her.
[4] When King Chungseon began his second reign as king in 1308, Cho's clan, the Pyongyang Cho clan, was listed as one of the fifteen great ministerial families (재상지종; 宰相之種; chaesang chi chong), eligible for marriage with the royal House of Wang.
