John Marshall Jones (July 20, 1820 – May 5, 1864) was a brigadier general in the Confederate States Army during the American Civil War.

From 1854 until 1855, he served on a board commissioned to revise rifle and light artillery military tactics, and received a promotion to captain on March 3, 1855.

With the outbreak of the Civil War and Virginia's secession, Jones resigned his commission in the United States Army on May 27, 1861, to enter the Confederate service as a captain of artillery.

During Johnson's assault on Culp's Hill at Gettysburg, Jones suffered a severe wound to his thigh that put him out of action.

In August, Robert E. Lee called Jones "a good commander" when he assigned him to lead the brigade vacated by William "Extra Billy" Smith, who had returned to Virginia as governor.
