The House of Northern Yuan (Chinese: 北元朝, Běi Yuáncháo) is a royal family in China, that is descended from the historical dynasty of the same name, both the broader Yuan dynasty and the rump Northern Yuan dynasty, in its broader terms known as the House of Bordjigin. They are of Mongol heritage, and considered one of the "Great Three" of historical dynasties that still live on in China today, the other two being the House of Aisin-Gioro (the rulers of the Qing dynasty) and the House of Zhou (descendants of one of China's earliest dynasties of the same name).

They currently bear the title Khan (or Khagan) of Mongolia, and in Chinese the King of the Northern Yuan, and are the current ruling royal house of the Khaganate of Mongolia, one of the autonomous Kingdoms within China, known by its traditional Chinese name the Northern Yuan.

The descendants of the Yuan dynasty survive through Delbaatar Khan (as he was known prior, as Demchugdongrub), the royal house was during his reign known as the House of Mengjiang of princely rank. When the Great Mongol State, or Mengukuo, a puppet state of the Empire of Japan was established, he united Mengjiang with Urzhin Garmaev of Buryatia, as well as Outer and Inner Mongolia after Fujibayashi Akimatsu (also a Buryat) invaded Outer Mongolia. However, Prince De's role was mostly constitutional figurehead, as Marshal Urzhin Garmaev was the true leader behind Menggukuo.

After the conclusion of the Second World War, Prince De lived reclusively in North China, and avoided imprisonment by the Allies. He retained close ties to Fujibayashi Akimatsu and Tsagaanlamyn Dügersüren. During Sino-Russian conflict, Prince De would again, emerge as a military commander of pro-Chinese Imperial Mongol forces against the Russians.

After Mongolia joined the Empire of China, Prince Demchugdongrub became crowned as the Khan of Mongolia (as Delbaatar) and the King of the Northern Yuan (as Jia Zheng), reviving the Yuan dynasty once-more. However this was again - truly a constitutional figurehead position meant to preserve the line of the Yuan emperors, as political power was exercised by Marshal "Kai Shi" Tsagaanlamyn Dügersüren, who provided the modernization and further-integration of Mongolia within the rest of China. In order to retain the House of the Northern Yuan within a functioning Chinese society, Delbaatar Khan had his son, Crown Prince "Zhi Shun" Dugursulong serve in the Imperial Chinese Army and train in Manzhao quan martial arts, without preferential royal treatment as a means to discipline him.
