The Haeju Oh (海州 吳氏) trace their descent to Oh In-yu (吳仁裕), a scholar who came from Song China during the reign of King Seongjong of Goryeo and won fame for his learning. Settling in Haeju in Hwanghae Province, his descendants took Haeju as their clan seat. In the 2015 census they numbered about 460,000 — the largest of Korea's Oh lineages.
The clan divides broadly into the Gyeong-pa (京派) and the Hyang-pa (鄕派). The more numerous Gyeong-pa descends from Oh In-yu and split further into sub-branches such as the Daehogun-gong and Chanseong-gong lines; the Hyang-pa is held to form a separate lineage.
After the Injo Restoration the Haeju Oh flourished as a leading family of the Westerner (Seoin) faction, producing several chief councillors and Grand Academicians. From this clan came Oh Yun-gyeom (吳允謙), a celebrated chief state councillor; Oh Dal-je (吳達濟), one of the Three Scholars who opposed peace with Qing during the 1636 Manchu invasion and died a martyr; Oh Myeong-hang (吳命恒), a merit subject who suppressed Yi In-jwa's rebellion; and Oh Se-chang (吳世昌), a calligrapher, journalist and one of the 33 national representatives of the March First Movement.
Their settlements are found across Gyeonggi, Chungcheong, Jeolla and Gyeongsang, with notable villages in Yongin, Gongju and Anseong.
