Alan Stephenson Boyd (July 20, 1922 – October 18, 2020) was an American attorney and transportation executive who led several large corporations and also served the U.S. Government in various transportation-related positions.

Additionally, he served in executive positions with the Civil Aeronautics Board, the U.S. Department of Commerce, and was a president of Amtrak.

He subsequently joined the United States Army Air Forces in 1942 and remained there through the end of World War II.

He was unpopular with labor leaders when he advocated reducing government restrictions on the maritime industry, and when he denounced featherbedding by railroad workers.

[5] The federal government investigated the potential conflict of interest because that railroad had received aid from Boyd's department before he resigned, but no wrongdoing was found.

[8] He became the chairman of Warner Blue & Mahan, a Washington, D.C.–based consulting firm working on new technology ventures, in 1994.

He also received the 2009 Philip J. Klass Award for Lifetime Achievement from Aviation Week & Space Technology.
