Carl Boyd (born 1936) is an American historian whose work has focused on military, diplomatic, and intelligence history, particularly German-Japanese relations during the Second World War.
Boyd joined the history faculty of Old Dominion University in 1975. He was named an Eminent Scholar at the university in 1994 and Louis I. Jaffé Professor of History in 1995.
Boyd's research has included German–Japanese relations, military intelligence, and submarine warfare. He has described his approach to military history as Clausewitzian, emphasizing the political and diplomatic dimensions of warfare alongside military operations. His 1993 book, Hitler's Japanese Confidant: General Ōshima Hiroshi and MAGIC Intelligence, 1941–1945, examined Japanese–German relations using intercepted Japanese diplomatic communications. He also wrote The Japanese Submarine Force and World War II with Akihiko Yoshida.
