Amos Beebe Eaton (May 12, 1806 – February 21, 1877) was a career officer in the United States Army, serving as a general for the Union during the American Civil War.

Appointed a lieutenant colonel and assistant commissary general in 1861, Eaton was given the task of creating an effective supply system for the fledgling Union army.

[2] On March 8, 1866, President Andrew Johnson nominated Eaton for appointment to the brevet grade of major general to rank from March 13, 1865, and the U.S. Senate confirmed the nomination on May 4, 1866, and re-confirmed it on July 14, 1866, in order to have line officers precede staff officers in rank.

His daughter Frances Spencer Eaton married Charles Atwood White, the great-grandson of American founding father Roger Sherman.

His grandson, Dr. George Francis Eaton (son of Daniel), earned his Ph.D. from Yale University and was an instructor at that institute.

His 3rd great-grandson, Staff Sergeant Richard Selden Eaton, Jr. (1966-2003), was a United States Army counterintelligence analyst who died in Iraq from illness while active service.
