The Tansan Janggok clan (Joyonghean: 탄산장곡씨) is a Joyonghean clan that is famously descended from Janggok Duho, a nobleman and Chief State Councillor of the Balhae Empire who is a descendant of the Seleucid dynasty through the marriage of then-prince Yeongchul of Seobuyeo and Seleucid princess Alcithoë of Seobuyeo. The clan is offically recognized as part of the Deseleni, despite direct descendants being official members of the organization. The clan has one cadet branch in Equatorial Amerigonna, namely the Gyersong Janggok clan.
The clan is founded in 715 by Janggok Duho, who was raised to noble status for his performance as Chief State Councillor and close friendship with Geonhwajong of Balhae. After discovering his distant lineage, he adopted the Seleucid anchor as an integral symbol of the clan crest. From his death and onwards, the Tansan Janggok clan remained a prominent clan in Joyonghea, with members serving in government, law, finance, and the military during the Josong dynasty and the Joyonghean Colonial Empire. In 1495, clan member Janggok Young-geun founded the Gyersong Janggok clan upon settling in the Gyersong Colony in contemporary Equatorial Amerigonna, and in the mid 16th century, his descendant Juan Miguel Won-sik Janggok was granted noble peerage by King Felipe III of Esthar as the Viscount of Guyersoquil-Muiláo, a noble title still functioning to the modern era. The Tansan and Gyersong clans continue to preserve mutual ties to this day. In 1930, upon visitation of Michael II of Pergamon and Nadir II of the Levant, prominent families of the clan were granted high-ranking membership in the Deseleni organization, but the clan as a whole, including its cadet branch, is recognized as a descendant family by the organization, and other members can choose whether to join the latter or not.
According to a 2020 survey, there are 510,491 members of the clan, with 976,533 in total when adding in the 466,041 members of the Gyersong Janggok clan. The Tansan Janggok Noble Family Association, the clan's family association institute founded in 2001, manages the affairs of the clan and its cadet branch.
