Yuan Zhen (died 10 April 370), courtesy name Yanren, was a Chinese military general of the Eastern Jin dynasty.
Yuan Zhen allied himself with Jiang Bin (江虨), Zhu Dao (朱燾) and Mao Muzhi, and together they put down the rebellion.
Later in 356, Yuan Zhen, now as Dragon-Soaring General, helped repair the imperial tombs in Luoyang after Huan Wen successfully captured the city.
The Yan general Lü Hu (呂護) attacked Luoyang in 362, so Yuan Zhen assisted by keeping the ancient capital supplied with rice before falling back to Shouchun.
Huan Wen ordered Yuan Zhen to defend Pengcheng while carving out a road to help the transport of supplies.
During the campaign, Huan Wen was faced with a recurring problem as his supply routes were held back by a drought that made the rivers too shallow for his ships to sail.
Huan Wen sent Yuan Zhen to attack Qiao and Liangguo commanderies to open up the dam at Shimen (石門; north of present-day Fuyang, Anhui) and allow water to flow through the rivers.
He fully blamed Yuan Zhen for not securing his supply route, but part of this also had to do with Huan Wen wanting to save face and deflect fault.
[7] Former Yan was first to receive his submission, and wanted to make Yuan Zhen Commissioner Bearing Credentials and a few other important titles.
His son Yuan Qin (袁瑾) would succeed him after the Administrator of Chen Commandery, Zhu Fu (朱輔) acclaimed him.
