James David Mooney (18 February 1884 – 21 September 1957) was an American engineer and corporate executive at General Motors who played a role in international affairs in the 1930s and early 1940s.

Born in Cleveland, Ohio, Mooney started classes in 1904 at the Case School of Applied Sciences, majoring in mining engineering, but did not graduate in the traditional 4 year period.

He arranged for a meeting in London between Helmuth Wohlthat, who was working for Hermann Göring on the Four Year Plan for the German economy, and ambassador Joseph Kennedy.

[6] Early in August 1940, the recently founded PM Magazine, published a series of articles that attacked Mooney for his contacts with the Nazis.

The magazine accused him of pro-German views and criticized a speech he had made, later printed as an article in the Saturday Evening Post, entitled "War or Peace in America?

"[1] In 1940, Mooney resigned from his position as President of General Motors Overseas to head a small team of directors charged with gearing up GM for wartime production.
