Kim In-gwan (金仁琯) is the founder of the Taesa-gong branch (太師公派) of the Gyeongju Kim clan. He served around the reign of King Yejong of Goryeo as Acting Grand Tutor to the Crown Prince (檢校太子太師). The most flourishing of the clan's branches, it gave rise to major lines such as the Sangchon-gong branch (桑村公派). His exact genealogical link to King Gyeongsun is not, however, fully documented.
