Prince Jari (Korean: 자리군; Hanja: 資利君) was a Korean Royal Prince as the youngest son of Taejo of Goryeo and Lady Seongmu of the Pyeongsan Bak clan.[1] His religion was Buddhism. He died too early at the young age since Ja-ri (자리; 資利) mean was the youngest son,[2] so it seems that he was the youngest son of Taejo among his 25 sons.
