Little Round Top is the smaller of two rocky hills south of Gettysburg, Pennsylvania—the companion to the adjacent, taller hill named Big Round Top. It was the site of an unsuccessful assault by Confederate troops against the Union left flank on July 2, 1863, the second day of the Battle of Gettysburg, during the American Civil War.

The Battle of Gettysburg was a three-day battle in the American Civil War fought between Union and Confederate forces between July 1 and July 3, 1863, in and around Gettysburg, Pennsylvania. The battle, which was won by the Union, is widely considered the Civil War's turning point, ending the Confederacy's aspirations to establish an independent nation. It was the Civil War's bloodiest battle, claiming over 50,000 combined casualties over three days.
