Naghachu (ᠨᠠᠭᠠᠴᠦ Mongolian: Naγaču; Chinese: 納哈出; d. 31 August 1388[1]), also written as Nahacu, was an ethnic Mongol leader and general of the Northern Yuan in Manchuria, which was under Liaoyang province of the former Yuan dynasty. Originally a Yuan official, he had won hegemony over the Mongol tribes in a wide area including much of Rehe and Liaoning by the mid-1380s. Now he grew strong in the northeast, with forces large enough (numbering hundreds of thousands) to threaten invasion of the newly founded Ming dynasty in order to restore the Mongols to power in China proper. Instead of waiting for the Northern Yuan to attack, in 1387 the Ming sent a military campaign to attack Naghachu and forced his surrender[2] after successful diplomacy. Naghachu and thousands of his officers and relatives were sent to Nanjing, the capital of the Ming dynasty at that time. The Ming granted Naghachu himself a marquisate with a stipend of 2,000 piculs of grain, estate of public fields in Jiangxi, and a mansion in Nanjing. He died near Wuchang on 31 August 1388, probably from overindulgence in alcohol, and was buried outside Nanjing.[3]
辛丑，海西侯納哈出卒。納哈出性嗜燒酒，飲常過度。當盛夏時，每以水沃身，因得疾。上命醫療之而愈，常戒其飲。至是，從征南將軍頴國公傅友德等往征雲南，飲酒如初，行至武昌，疾復作，卒於舟中。上聞而憫之，詔歸其柩于京師，葬都城南門外。
