Yam O (Chinese: 陰澳) is a bay located on the northeast shore of Lantau Island, in the New Territories of Hong Kong. It is part of the Ma Wan constituency of the Tsuen Wan District Council. Yam O was the only natural lumber preservation zone in Hong Kong. Even today, travellers passing through Yam O can see natural lumber on stilts in the bay. Today, Yam O is known for its interchange for the Disneyland Resort line via the nearby Sunny Bay MTR station, built on reclaimed land near Yam O.
