Commodore William Henry Alexander Macomb (6 June 1819 – 12 August 1872) was an officer in the United States Navy who served during the American Civil War.
Born in Michigan, Macomb was the son of Major General Alexander Macomb, who served as commanding general of the United States Army. He married Mary E. Stanton on 17 January 1844 in Fort Hamilton, New York.
Macomb served with distinction during the Civil War. He took part in the riverine warfare along the Mississippi, commanded Shamrock in the North Atlantic Blockading Squadron, headed the naval force which captured Plymouth, North Carolina, and led an expedition up the Roanoke River in North Carolina. For his gallantry in action with the North Atlantic Squadron, he was advanced several numbers in his grade.
Commodore Macomb died in Philadelphia, Pennsylvania.
In 1941, the destroyer USS Macomb (DD-458) was named in honor of Commodore Macomb and his first cousin, Rear Admiral David B. Macomb (1827–1911).
