The name "Busan" is the Revised Romanization of the city's Korean name since the late 15th century. It officially replaced the earlier McCune-Reischauer romanization Pusan in 2000. During the Japanese period it was spelled "Fuzan".  The name 釜山 (now written 부산 using the Korean alphabet) is Sino-Korean for "Cauldron Mountain", believed to be a former name of Mt Hwangryeong (황령산, 荒嶺山, Hwangryeong-san) west of the city center. The area's ancient state Mt Geochil (거칠산국, 居柒山國, Geochilsan-guk, "Rough-Mountain Land") is similarly thought to refer to the same mountain, which towers over the town's harbor on the Suyeong. (The later Silla district of Geochilsan-gun was renamed Dongnae in 757.)

"Busan" is the romanization of the city's Korean name - 부산.  Previously, the name was romanized as "Pusan" until it was officially replaced in 2000.  The meaning of the name in Sino-Korean is "Cauldron Mountain", believed to be the former name of a nearby mountain now known as Mt Hwangryeong (황령산).
