The Ansan Kim clan (Korean: 안산 김씨; Hanja: 安山 金氏) is a Korean clan, that was an aristocratic family from the Goryeo era.
They wielded their influence over the country's affairs primarily in the mid-11th century through marriages with the heirs of the kingdom.
Three of King Hyeonjong's queens, who reigned from 1009 to 1031, were from this family.
[1] The Gyeongwon Yi clan will eventually put an end to this dominance, as Yi Ja-yeon manages to marry three of his daughters to King Munjong, who reigned from 1046 to 1083.
[2] The modern-day Ansan Kim clan has a population of 16,990 in South Korea as of the 2015 census.
