Orr's Rifles was a South Carolina infantry regiment that served in the Confederate States Army during the American Civil War.

On 20 July 1861, James Lawrence Orr organized the First South Carolina Rifle Regiment at Sandy Springs.

First posted to Sullivan's Island, SC to defend Charleston Harbor, others called them the "Pound Cake Regiment" in reference to their "light" garrison duty.

Lee surrendered the ANV, including Orr's Rifles, at Appomattox Court House on 9 April 1865.
