The systematic transcription Kau Lung or Kau-lung was often used in derived place names before World War II, for example Kau-lung Bay instead of Kowloon Bay. Other spellings include Kauloong, Kawloong

The name Kowloon stems from the nine dragons, a term which refers to eight mountains and a Chinese emperor: Kowloon Peak, Tung Shan, Tate's Cairn, Temple Hill, Unicorn Ridge, Lion Rock, Beacon Hill, Crow's Nest and Emperor Bing (Song Dynasty).
