Jeffrey Guy Grey (19 March 1959 – 26 July 2016) was an Australian military historian. He wrote two volumes of The Official History of Australia's Involvement in Southeast Asian Conflicts 1948–1975, and several other high-profile works on Australia's military history. He was the first non-American to become the president of the Society for Military History, but is perhaps best known as the author of A Military History of Australia (first edition 1990).
