Charles William Maynes (December 9, 1938 – June 2, 2007) was a United States diplomat and long-time editor of Foreign Policy magazine.
He was then awarded a Rhodes Scholarship and studied at Merton College, Oxford, receiving a master's degree in politics, philosophy, and economics in 1962.
In 1972, he left the foreign service to join the staff of Sargent Shriver, the running mate of Democratic candidate George McGovern in the 1972 presidential election.
During his time in office, Maynes helped draft agreements that led to the independence of Namibia from South Africa.
Leaving government service in 1980, Maynes became editor of Foreign Policy magazine, a position he would hold until 1997.
