Shelby's Raid, also known as Shelby's Great Raid, was a Confederate cavalry incursion into Arkansas and Missouri during the American Civil War in 1863. Led by Colonel Joseph Orville Shelby, the raid took place from August 21, 1863, to November 3, 1863, covering over 800 miles across territories in west central and northwest Arkansas, as well as southwest and west central Missouri.

Joseph Orville "J.O." Shelby was a senior officer of the Confederate States Army who commanded cavalry in the Trans-Mississippi Theater of the American Civil War. After the Confederacy surrendered, Shelby tried to swear fealty to Emperor Maximilian I during the French invasion of Mexico. With the Emperor's permission, Shelby formed a colony of Confederate exiles in Mexico until the defeat of the French, then abandoned the operation.
