Augustine Nguyễn Lạc Hóa (c. 1901 – c. 1993) was a refugee Chinese Catholic priest, who arrived in South Vietnam in 1959 and led a militia called the Sea Swallows resisting the Viet Cong in the Ca Mau Peninsula. The "fighting priest" and his "village that refused to die" attracted admiring media stories in the United States, and in 1964 he received the Ramon Magsaysay Award in the Public Service category.
