The Wonju Won clan () is a Korean clan. Their Bon-gwan is in Wonju, Gangwon Province. The clan was a prominent yangban family during Korea's Joseon dynasty.
According to the research held in 2015, the number of the Wonju Won clan was 126,677. Their founder was Wà Ân Kà Âkyu (), a key figure during Taejo of GoryeoâÂÂs reign, and Wà Ân Ikkyà Âm () who made Wà Ân Kyà Âng () the progenitor of the clan. Wà Ân Kyà Âng was dispatched by Emperor Taizong of Tang in Tang dynasty as one of the Hanlin Academy.
All three men have separate lines that were called Wongokgonggye (ìÂÂ곡공ê³Â, èÂÂ谷堬系) through Wà Ân Kyà Âng, Wonseongbaekgye (ìÂÂì±백ê³Â, Ã¥ÂÂÃ¥ÂÂ伯系) through Wà Ân Kà Âkyu, and Sijunggonggye (ìÂÂì¤Âê³µê³Â, ä¾Âä¸Â堬系) through Wà Ân Ikkyà Âm. But these lines were eventually, formally, divided into branches; Wongok Baekpa (ìÂÂì±백ÃÂÂ, Ã¥ÂÂÃ¥ÂÂ伯派), Wonseong Baekpa (ìÂÂì±백ÃÂÂ, Ã¥ÂÂÃ¥ÂÂ伯派), and Sijung Gongpa (ìÂÂì¤Âê³µÃÂÂ, ä¾Âä¸Â堬派).
