Gouverneur Kemble Warren (January 8, 1830 – August 8, 1882) was a civil engineer and prominent general in the Union Army during the American Civil War. He is best remembered for arranging the last-minute defense of Little Round Top during the Battle of Gettysburg and is often referred to as the "Hero of Little Round Top." His subsequent service as a corps commander and his remaining military career were ruined during the Battle of Five Forks, when he was relieved of command by Philip Sheridan.
