Rambler Channel is a body of water in Hong Kong that separates Tsing Yi Island from mainland Kowloon Peninsula, namely Tsuen Wan and Kwai Chung in the New Territories. The channel separates the two landmasses by 900 metres at its widest point. Historically, the channel was known as Tsing Yi Mun and Tsing Yi Channel.
The shoreline of the channel has changed rapidly in the last several decades, owing to the development of Tsuen Wan New Town and the Kwai Chung Container Port. Before extensive reclamation, Gin Drinkers Bay was located along the eastern shore of the channel, and Tsing Yi Bay was located along the western shore. Three islands (Nga Ying Chau, Pillar Island and Mong Chau) once stood in the channel as well.
