Sinchon Kang clan (Korean: 신천 강씨; Hanja: 信川 康氏) is a Korean clan from Sinchon County, Hwanghae Province.
According to a census held in 2015, the clan has 52,945 members and in a census held in 2000, the clan had 13,909 families.
The daedongbo (a compilation genealogy book of related clans) of the Sinchon Kang clan claims that Kang Ho-gyŏng was the 67th generation descendant of Kang Hou (강후; 康侯), a grandson of King Wen of the Zhou dynasty.
However, the historical veracity of that claim cannot be verified.
[1] Furthermore, the intermediate ancestor (중시조) of the Sinchon Kang clan is considered to be Kang Chi-yŏn, a 14th generation descendant of Kang Ho-gyŏng.
