Kowloon Bay (Chinese: 九龍灣; Jyutping: Gau Lung Waan) is a bay and a town in Hong Kong.
The bay is located at the east of the Kowloon Peninsula and north of Hong Kong Island. It is the eastern portion of Victoria Harbour, between Hung Hom and Lei Yue Mun. The bay was divided into half when the runway of the former Kai Tak International Airport was constructed in the middle of the bay.
The reclamation of north-eastern Kowloon Bay near Ngau Tau Kok is also named Kowloon Bay. It was formerly known as Ngau Tau Kok Industrial Area. After the construction of MTR Kowloon Bay Station, the area is referred as Kowloon Bay. The area near the MTR station is residential while the area near the shore is industrial. The area is traditionally an extension of Ngau Tau Kok, and thus facilities such as Ngau Tau Kok Police Station are located there.
Administratively, the reclamation of Kowloon Bay and water east of the runway except the airport area is part of Kwun Tong District. The airport and the waters of the district, on the other hand, belong to Kowloon City District.
The bay has undergone massive reclamation over the past century. Even San Po Kong, which is now far from the coast, was reclaimed from the bay in the early days.
The western part of the bay is now protected from the sea by a breakwater, and forms the To Kwa Wan typhoon shelter. A small barrel rock, the Kowloon Rock, is in the typhoon shelter. Other barrel rocks, the Channel Rock and the Hoi Sham Island (also To Kwa Wan Island), are now connected to land at the former Kai Tak International Airport runway and at To Kwa Wan respectively, by land reclamation.
