The Gangneung Kim clan () is a Korean clan, with the bon-gwan (ancestral seat) based in Gangneung, Gangwon Province, South Korea.
The progenitor of the clan is considered to be Kim Chu-wà Ân. Kim Chu-wà Ân was the relative of Hyegong of Silla and the rightful heir to the throne. However, as Kim did not reside in the capital of Gyeongju, he needed to cross the Alcheon River (modern-day ) to be proclaimed king after death of King Seondeok of Silla. Due to heavy rainfall, the river was flooded and Kim Chu-wà Ân could not cross and make it to the capital. The nobles of Gyeongju instead picked Kim Kyà Âng-sin to be the new king. Kim Chu-wà Ân was compensated by being enfeoffed as the Prince of Myà Ângju (modern-day Gangneung).
As a part of the Silla royalty, they were true bone caste in Silla's bone-rank system. In 822, Kim Chu-wà Ân's son, Kim Hà Ân-ch'ang, rebelled against the Silla government and attempted to create his own kingdom of Jangan, based in Ungju. Kim Hà Ân-ch'ang was defeated and he committed suicide to avoid capture. 239 of his relatives were killed. His son, Kim Pà Âm-mun, also attempted a rebellion against Silla 3 years later at Hansan near Seoul, but he too failed.
A majority of the clan is descended from Kim Chu-wà Ân's third son, Kim Sin () who chose to stay in Gangneung. The Gangneung Kims still residing in Gangneung would become the regional lords or hojoks of Gangneung, taking advantage of their true bone status. They were key supporters of Wang Kà Ân, with individuals such as Kim Ye and Kim Sun-sik contributing to the founding of Goryeo. The grateful Wang Kà Ân granted a branch of the Gangneung Kim clan with his own surname of Wang, who were known as the Gangneung Wang clan. During the early Goryeo period from 981 to 1146, they produced nine government officials, five of whom were high officials, making them the clan with the fifth most officials produced in this timeframe.
In the 2015 South Korean census, 179,593 individuals who were members of the Gangneung Kim clan.
