Grand Prince Chinan (Korean: 진안대군; Hanja: 鎭安大君; 1354 – 15 January 1394), personal name Yi Pangu (이방우; 李芳雨), was a nobleman during the late Goryeo dynasty who become a prince of Joseon as the first son of King Taejo and Queen Sinui.
He became the general secretary of the last king of Goryeo dynasty. In year 1388, his father, Yi Sŏnggye, overthrew the Goryeo dynasty. After witnessing this incident, he went to Bogae mountain in Cheorwon to retire. Later on, he went to live at Hamheung, which is located in present-day North Korea; there, he died at the age of 40 in 1394.
In 1392, when his father established the Joseon Dynasty and was giving out royal titles, his first son became as known as Grand Prince Chinan.
In the annals of Joseon dynasty, it describes Grand Prince Chinan as a man who liked alcoholic beverages, and states that he drank copious amount until he died. However, according to a memorial stone of Grand Prince Chinan, which was made in 1789, "Grand Prince Chinan was an exemplary son to his parent, who took good care of his brothers and sisters. When he grew older, he minded in literature and practiced humble life style and did not fancy wealth nor authority."
