Jangchungdan Park, Public park in Jung District, Seoul, South Korea

Jangchungdan Park lies between Dongguk University and the Shilla Hotel on the northern slope of Namsan. It holds the Jangchungdan Monument, Seoul Tangible Cultural Property No. 1, moved beside the relocated Supyo Bridge in 1969. The grounds also contain a senior citizens' hall, sports facilities, an outdoor stage, and statues of Samyeongdaesa, Yi Jun, Yi Han-eung and Yu Gwan-sun.

Gojong of the Korean Empire founded the Jangchungdan shrine in September 1900 on the site of Namsoyeong, a southern guard post, to honour officials and soldiers killed during the 1895 assassination of Empress Myeongseong. Rites were held each spring and autumn. Japan halted the ceremonies in 1908, and after annexation the area was planted with cherry trees in 1919 and turned into a Japanese-style park.

The park holds monuments dedicated to Korean independence and the people who fought for it during colonial times. These memorials are scattered throughout the grounds for visitors to discover.

The park lies between Dongguk University and the Shilla Hotel, with the nearest subway stop at Dongguk University Station on Line 3. The Jangchungdan Monument stands by the water clock bridge near the entrance, and the senior hall, sports facilities and outdoor stage are further inside.

The stone marker at the park entrance, Seoul Tangible Cultural Property No. 1, bears the characters "Jangchungdan" written by Crown Prince Sunjong, with an inscription by Min Yeong-hwan on the reverse. The original shrine site is lost; it is thought to have stood near the children's baseball field at the park's south end.
