Patrick Henry Nelson (July 26, 1824 – June 24, 1864) was a Confederate States Army officer and militia general from South Carolina during the American Civil War.

[3] With the reorganization and enlargement of the Confederate Army, Nelson was made lieutenant colonel of the 7th South Carolina Infantry Battalion in 1862.

In 1864, Nelson was assigned to Brigadier General Johnson Hagood's Brigade when the battalion was ordered to Virginia in the spring.

On June 24, 1864, in the Siege of Petersburg, Nelson led an attack of 400 men on the extreme right of the Union lines near the Appomattox River.
