Coordinates: 35°10′00″N 129°3′24″E / 35.16667°N 129.05667°E Busan Citizens Park (formerly Camp Hialeah) is a former Imperial Japanese Army base and United States Army camp located in the Busanjin District of the city of Busan, South Korea. The Camp occupying 133-acre (540,000 m2) of prime real estate was closed on 10 August 2006 and handed back to the Busan city government. It was redeveloped as the Busan Citizens Park (Korean: 부산시민공원) and opened on 1 May 2014.
During the Japanese occupation of Korea, a horse racing track encircling the main area of the Camp was owned by the Chōsen Racing Association. A visiting American sailor is purported to have named the camp after the Hialeah Park Race Track in Hialeah, Florida.
The area served as the Imperial Japanese Army headquarters in Busan until the surrender of Japan.
U.S. troops took command of Camp Hialeah on 17 September 1945 and remained until the end of 1948 when control of the installation passed to the U.S. Consulate and the United Nations.
Busan was a critical strategic and logistical staging area during the Korean War. By 5 September 1950, the Korean People's Army held most of the Korean peninsula, except for the U.N. forces beachhead around the Pusan Perimeter. Busan port facilities were under the control of the U.S. military to handle the enormous support requirements of the fighting forces, with the 8069th Replacement Depot operating Camp Hialeah. After the Korean Armistice Agreement was signed on 27 July 1953, most of the Busan port facilities were turned over to the ROK government.
