Park Chun-jang (朴春長, 1595-1664) was a scholar of the Jinwon Park, courtesy name Eonseung and pen name Donggye. His father Park Geun-hyo is said to have been named county magistrate for military merit in the Imjin War, and his mother was a daughter of Yi Yu-gyeom of the Hampyeong Yi. Orphaned early, at thirty he felt shame at lacking learning and first studied under his eldest brother Park Chun-su, then at thirty-six under An Bang-jun.
In the 1636 Second Manchu invasion he joined An Bang-jun's call but returned home on hearing that Namhansanseong had fallen, sending the governor Won Du-pyo an eight-article letter showing his patriotism. He passed the sama examination in 1645 and in 1652 (Hyojong 3) submitted a five-article memorial to correct current ills, which was not carried out. He is regarded as consistent in his thought of honoring the king and punishing rebels.
In 1657 he published the Jeongyubo, the oldest surviving Jinwon Park genealogy, which admits it could not record the founder's deeds in detail but shows that earlier genealogies existed. In the great famine of 1662 he reported the people's plight as it was and led relief, and in later years he built a study under Yongsan at home and trained pupils. His Donggye Yugo survives; he is enshrined at Yukhyeonsa, and Park Jin-hyeong and Park Sa-heon were his notable pupils. Namu Wiki credits him with a gazetteer, the Sanyangji, which could not be confirmed in official sources.
The Jeongyubo, published in 1657, is the oldest surviving Jinwon Park genealogy and was issued by Park Chun-jang. While admitting that the founder's line could not be known in detail, it shows that earlier genealogies existed, and it became the starting point of later compilations such as the 1737 Jeongsabo revision.
In the Second Manchu invasion Park Chun-jang wrote to the governor Won Du-pyo, and in 1652 he submitted a five-article memorial on correcting current ills, which was not accepted. In the 1662 great famine he is said to have reported local conditions as they were and sought relief for the people.
The tomb was not confirmed. He is said to be enshrined at Yukhyeonsa.
