Admiral Louis Rodolph de Steiguer (March 18, 1867 – April 20, 1947) was an officer in the U.S. Navy. He was Commander-in-Chief of the U.S. Battle Fleet from 1927 to 1928.

Born in Athens, Ohio, on March 18, 1867, to Judge Rodolph de Steiguer and Mary Carpenter de Steiguer, he was descended from Judge Silvanus Ames, a prominent citizen of southern Ohio. He was appointed to the U.S. Naval Academy from Ohio in 1885. Graduating in 1889, he served his naval cadet cruise aboard the new steel cruiser Atlanta, which sailed with the Squadron of Evolution to Europe, the Mediterranean and Brazil, before returning to New York in 1890. He was commissioned ensign on July 1, 1891, and served in various assignments ashore and afloat, including tours aboard the Vulcan and aboard the Montgomery during the Spanish–American War. Promoted to lieutenant commander in 1905, he was Supervisor of New York Harbor from December 9, 1905, to August 30, 1906; was in charge of the Fifth Lighthouse District in 1911; commanded the Panther through 1913; was acting commandant of the Norfolk Naval Shipyard from September 25, 1914, to January 4, 1915; and commanded the battleship Kearsarge in 1916.

During World War I he served as chief of staff of the Third Naval District before reporting as captain of the battleship Arkansas, which was stationed with the American dreadnought squadron operating with the British Grand Fleet. After the war, de Steiguer was Hydrographer of the Navy from July 1921 to December 1921. Promoted to rear admiral, he was commander of the First Naval District, including the Portsmouth Navy Yard, from June 1923 to 1925.
