George Crews McGhee (March 10, 1912 – July 4, 2005) was an American oilman and a career diplomat in the United States foreign service.

For a time McGhee worked for Conoco, on a crew that made the first oil discovery on the Gulf Coast using reflection seismology.

Back in the United States he became vice president of the National Geophysical Company, where he managed reflection seismology surveys in Cuba.

From November 1961 to April 1963, he served as the third ever Under Secretary of State for Political Affairs, during the Kennedy Administration (later to be replaced by W. Averell Harriman).

[5] In retirement McGhee wrote a semi-autobiographical novel, entitled The Dance of the Billions: A Novel About Texas, Houston, and Oil (1990), whose lack of success was attributed by his family to its puritanical tone.

His estate, Farmer's Delight in Loudoun County, Virginia, is operated by the McGhee Foundation as a museum, research center and meeting facility.
