Cobb's Legion (also known as the Georgia Legion) was an American Civil War Confederate States Army unit that was raised from the state of Georgia by Thomas Reade Rootes Cobb during the summer of 1861.

[1] A legion in the Civil War usually meant a combined-arms unit, consisting of two or three branches of the military: infantry, cavalry, and artillery.

[1] The legion concept was not practical for Civil War armies and, soon after Robert E. Lee took command of the Army of Northern Virginia on June 1, 1862, the individual elements were assigned to other units.

[1][2][3] After the infantry battalion was brought up to regimental strength the unit was assigned to Howell Cobb's brigade in Lafayette McLaws's Division of James Longstreet's Corps of the Army of Northern Virginia.

Howell Cobb was absent after the Battle of Malvern Hill in July 1862 until August 1862 and again in October 1862 before moving to another command.
