Bình Ngô đại cáo (Hán tự: 平吳大誥, literally: Great proclamation upon the pacification of the Wu) was an announcement written by Nguyễn Trãi in 1428, at Lê Lợi's behest and on Lê Lợi's behalf, to proclaim the Lam Sơn's victory over the Ming imperialists and affirm the independence of Đại Việt to its people.
