William John (Jack) Read, was an Australian Coastwatcher on Bougainville Island in New Guinea during World War II. He was awarded the Distinguished Service Cross by the United States for his service during World War II in the Solomon Islands campaign and the New Guinea campaign. His experiences and reports have become an important source for historians regarding the history of the coastwatchers.

The Coastwatchers, also known as the Coast Watch Organisation, Combined Field Intelligence Service or Section C, Allied Intelligence Bureau, were Allied military intelligence operatives stationed on remote Pacific islands during World War II to observe enemy movements and rescue stranded Allied personnel. They played a significant role in the Pacific Ocean theatre and South West Pacific theatre, particularly as an early warning network during the Guadalcanal campaign.
