The Ming invasion of Viet (Chinese: 明入越/平定交南), known in Vietnam as the Ming–Đại Ngu War (traditional Chinese: 大虞與明戰爭; simplified Chinese: 大虞与明战争; Vietnamese: Chiến tranh Đại Ngu–Đại Minh / cuộc xâm lược của nhà Minh 1406–1407; Hán Nôm: 戰爭大虞 – 大明) was a military campaign against the kingdom of Đại Ngu (present-day northern Vietnam) under the Hồ dynasty by the Ming dynasty of China. The campaign began with Ming intervention in support of a rival faction to the Hồ dynasty which ruled Đại Ngu, but ended with the incorporation of Đại Ngu into the Ming dynasty as the province of Jiaozhi. The invasion is acknowledged by recent historians as one of the most important wars of the late medieval period, whereas both sides, especially the Ming, used the most advanced weapons in the world at the time.

A few years prior to the invasion, Hồ Quý Ly usurped the throne of the Trần dynasty of the Dai Viet, which led to the intercession of the Ming government to re-establish the Trần. However, Hồ forces attacked the Ming convoy escorting a Trần pretender, and all were killed in the attack. After this, the Yongle Emperor appointed Marquises Zhang Fu to prepare and lead the Ming armies for the invasion of Đại Ngu. The war lasted from 1406 to 1407, resulting in the Ming conquest of Đại Ngu and the capture of Hồ Quý Ly, his princes and members of the Hồ family.
