William Murray Black (December 8, 1855 – September 24, 1933) was a career officer in the United States Army, noted for his ability to organize and train young engineers.

Black, born in Lancaster, Pennsylvania, graduated first in the United States Military Academy class of 1877 and was commissioned in the Corps of Engineers.

As Chief Engineer under Generals William Ludlow and Leonard Wood (1899–1901), and six years later as advisor to the Cuban Department of Public Works, he modernized Havana's sanitary system.

For this work he was awarded the Army Distinguished Service Medal,[2] the citation for which reads: The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Major General William Murray Black, United States Army, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility as Chief of Engineers, in planning and administering the engineer and military railway services during World War I.
