Prince Imhae (20 September 1572 – 3 June 1609;[3] personal name Yi Jin, childhood name Yi Jin-Guk), was a Joseon Royal Prince as the eldest son of King Seonjo[4] and the elder brother of King Gwanghae. He was known for such a violent and arrogant personality, that he murdered some government officials alongside his half brothers: Prince Jeongwon (정원군) and Prince Sunhwa (순화군), but were survived[clarification needed] under their father's protection.[5] Also, when his depravity led to government officials demanding severe punishment for his actions, he was able to avoid such punishment by his father's protection too.

However, he was passed over for the Crown Prince's role in favour of his younger brother who would eventually take the throne and became King Gwanghae. After investigated for crimes he committed against common people, he was sent into exile to Gyodong County after the Imjin war, then died in 1609
