John Gould Moyer (July 12, 1893 – January 21, 1976) was an United States Navy Rear admiral, and the 31st Governor of American Samoa from June 5, 1942 to February 8, 1944. He was born in Chicago, Illinois, but lived in both Indiana and Hawaii for much of his life. Moyer was admitted to the United States Naval Academy on June 16, 1910, and became an Ensign shortly upon graduation. He became a Commander in 1934, a Captain in 1939, and eventually a Rear admiral. During his governorship, Moyer recommended the tour of duty of the men under his command be reduced, and took over command of the United States Marines barracks previously under the control of Brigadier general Henry Louis Larsen.
