Gongsun Yuan (pronunciation^ⓘ) (died c.September 238^[1]), courtesy name Wenyi, was a Chinese military general, politician, and warlord who lived in the state of Cao Wei during the Three Kingdoms period of China. He rebelled against Wei in 237 and declared himself "King of Yan" (燕王). In 238, the Cao Wei general Sima Yi led forces to Liaodong and successfully conquered Yan.

^ Cao Rui's biography in Sanguozhi indicated that Sima Yi laid siege to Xiangping on the bingyin day of the 8th month of the 2nd year of the Jing'chu era. However, there is no bingyin day in that month; the next bingyin day is in the 9th month of that year and corresponds to 3 Sep 238 in the Julian calendar. Volume 74 of Zizhi Tongjian placed the fall of Xiangping on the renwu day of the 8th month of that year. However, there is also no renwu day in that month; the next renwu day is also in the 9th month and corresponds to 19 Sep 238 in the Julian calendar.
