John Cooper (July 24, 1828 – August 22, 1891) (born as John Laver Mather Cooper) was a member of the United States Navy. He is one of only nineteen people who have received the Medal of Honor twice and one of only fourteen to receive the Medal of Honor for two distinct events. His first such award came about because of his actions aboard the USS Brooklyn (1858) during the Battle of Mobile Bay, August 5, 1864. The second award was a result of an accidental fire in which Cooper advanced through the burning area in order to rescue a wounded man from certain death on April 26, 1865.
