Elwell Stephen Otis (March 25, 1838 - October 21, 1909) was a United States army officer who served in the American Civil War, Indian Wars, the Philippines late in the Spanish-American War and during the Philippine-American War, where he commanded the Eighth Corps. He served following the Philippine-American War as the Military Governor General of the Philippines. While not popular in the Philippines due to his authoritarian and 'pompous' manner, he was a skilled and capable administrator. Otis was replaced in the Philippines by the more popular Douglas MacArthur in 1900. Otis died in Rochester, New York on October 21, 1909 from painful angina.
