Hung Hom (traditional Chinese: 紅磡; simplified Chinese: 红磡; pinyin: Hóngkàn; Jyutping: hung4 ham3, red cliff) is an area of Kowloon, in Hong Kong, administratively part of the Kowloon City District, with a portion west of the railway in the Yau Tsim Mong District (油尖旺區). Hung Hom serves mainly residential purposes though is mixed with some industrial buildings in the north.
Hung Hom is in the southeast of the Kowloon Peninsula. It is bordered by Victoria Harbour in the south, King's Park in the west, Hung Hom Bay in the east, No. 12 Hill, Hok Yuen and the valley Lo Lung Hang. in the north.
Originally, Hung Hom was much smaller than the present-day context. Hung Hom Bay has been partially reclaimed several times since 1850, expanding the area of Hung Hom as a consequence. Rumsey Rock, formerly located in the bay, was buried in the reclamation process. Later a town was developed eastward parallel to the Hong Kong and Whampoa Dock.
Hong Hum was renamed to "Yamashita District" during the Japanese occupation from 1941 to 1945. It was one of the few places to be renamed.
