Dðáng Ngạn ÃÂá»Âch (, , , ?–1688) was a Chinese exile and seafarer who migrated to ÃÂại Viá»Ât in the late 17th century.
Dðáng Ngạn ÃÂá»Âch was a general of Ming China, native to Guangdong, and swore allegiance to Koxinga. His position was Chief Commander of Longmen (é¾ÂéÂÂ總堵, a place in modern Qinzhou, Guangxi). In 1679, after the Revolt of the Three Feudatories was put down by the Kangxi Emperor of the Qing dynasty, he led 3,000 soldiers and 50 ships that came to ÃÂàNẵng together with Hoàng Tiến (é»Âé²), Trần Thðợng Xuyên and Trần An Bình (é³å®Âå¹³), and "surrendered" to Nguyá» n Phúc Tần (although there is scholarly consensus that Phúc Tần had little choice in the matter).
Dðáng Ngạn ÃÂá»Âch and Hoàng Tiến were sponsored to Mỹ Tho by Phúc Tần, where ÃÂá»Âch served as chief of a small Chinese community. ÃÂá»Âch was murdered by his assistant Hoàng Tiến in 1688. Tiến then revolted against the new Nguyá» n lord, Nguyá» n Phúc Thái, but was eventually put down.
