Emile Lejeune (born 1853, date of death unknown) was a United States Navy sailor and a recipient of the United States military's highest decoration, the Medal of Honor. A native of France, Lejeune joined the U.S. Navy from New York. By June 6, 1876, he was serving as a seaman on the USS Plymouth. On that day, he and other crewmen took Plymouth's steam-powered launch to shore at Port Royal, South Carolina. While there, Lejeune rescued a civilian who had fallen off the Port Royal wharf. For this action, he was awarded the Medal of Honor three days later, on June 9.
