Cowie Bay (Malay: Teluk Cowie) is a bay on the east coast of the island of Borneo. It is a part of the Malaysian state of Sabah and flows into the Celebes Sea. Administratively, it belongs to the Tawau District in the Tawau Division.[1]
The bay covers an area of approximately 120 km2. At the end of the bay, there is an extensive shallow water area that is densely forested with mangrove swamps. The south side of the bay is bordered by Sebatik Island.[2]
The bay was named after William Clarke Cowie, who was an engineer, mariner, and businessman who helped establish British North Borneo and was Chairman of the British North Borneo Company.
