James Keith Marshall (April 17, 1839 – July 3, 1863) was a Confederate Army officer during the American Civil War.

Marshall commanded the wounded J. Johnston Pettigrew's brigade during Pickett's Charge at the Battle of Gettysburg and died during the assault.

[1] His great-grandfather had attended school with George Washington and was commander of the 3rd Virginia Infantry during the American Revolutionary War.

[2][3][4] Marshall accepted a commission as captain of Company M of the 1st North Carolina "Bethel Regiment" under Col. Daniel Harvey Hill in the spring of 1861.

After dispersing these men, a portion of the 52nd North Carolina fought part of the 8th New York Cavalry at Meal's Orchard.

After crossing Fairfield Road, Marshall's men slammed into the flank of the 121st Pennsylvania of Lt. Col. Alexander Biddle, routing them from the field and sending them running toward Seminary Ridge.

Just minutes later, as Marshall neared the stonewall on Cemetery Ridge he was struck in the forehead and killed instantly by two bullets while encouraging his men.
