Yang Nandi (died c.March 334[1]) was a ruler of Chouchi during the Jin dynasty (266–420) and Sixteen Kingdoms period.
Nandi met these with mixed results, sometimes having to resort to vassalage, but was ultimately successful in preserving the survival of Chouchi.
Nandi was the son of Yang Maosou, a Di chieftain from Qingshui County in Lueyang Commandery, who in 296, led his followers to Chouchi and declared independence during Qi Wannian's rebellion in Qinzhou and Yongzhou.
However, he was caught and executed by the provincial inspector, Zhang Guang (張光) when it was discovered that he had illegally sold a slave.
Both sides called for Chouchi to aid them and Maosou chose to support Zhang Guang in their conflict.
In the end, Nandi agreed to join Yang Hu but waited to catch Zhang Guang off guard.
Around the same time, the people of Liangzhou rose up against Nandi and ousted him back to Chouchi before surrendering their territory over to Cheng-Han.
Upon ascending the throne, Nandi chose to split command over the state between him and his younger brother, Yang Jiantou (楊堅頭).
Nandi brought his troops out to attack the invading army but was defeated, so he retreated back to his defenses.
Capitalizing his victory over Chen An in Qinzhou in 323, Liu Yao invaded Former Liang and Chouchi to keep up with his momentum.
In 327, the Zhao general Liu Lang (劉朗) attacked Chouchi but only captured very few territory before retreating.
This time, Cheng-Han managed to get Nandi to submit after capturing Yinping (陰平; present-day Wen County, Gansu) and Wudu.
