John Gould Moyer (July 12, 1893 – January 21, 1976) was a United States Navy Rear admiral, and the governor of American Samoa from June 5, 1942, to February 8, 1944.

Moyer was admitted to the United States Naval Academy on June 16, 1910, and became an Ensign shortly upon graduation.

[1] He was born to Eva Gould Moyer; his grandfather was a longtime district judge in Indiana.

During his governorship, Moyer suggested the tour of duty for military personnel in American Samoa be reduced from 18 to 12 months, believing that "the climate is bad for most Caucasians".

[1] As the Pacific War drew westward, Moyer took control of the United States Marine barracks on the island, a command previously held by Henry Louis Larsen, a man with the short-lived position of Military Governor of Tutuila.
