The 19th (Dawson's) Arkansas Infantry (1861–1865) was a Confederate Army infantry regiment during the American Civil War. The regiment was present for but not engaged during the Battle of Pea Ridge. At the Battle of Arkansas Post, the regiment became split, with part of the regiment surrendering with the garrison when the post capitulated. The captured portion of the regiment was eventually exchanged and released on the east side of the Mississippi and served the remainder of the war with the Confederate Army of Tennessee. The un-captured portion of the regiment was consolidated with the remnants of the 24th Arkansas and served the remainder of the war in the Department of the Trans-Mississippi.

The 2nd Arkansas Infantry was an army regiment of the Confederate Army during the American Civil War. The regiment was raised in May 1861 under Colonel Thomas C. Hindman. It served throughout the war in the western theater, in the Confederate Army of Tennessee, seeing action in the Kentucky, Tennessee and Georgia campaigns. Following its depletion in numbers, the regiment was consolidated several times with other Arkansas regiments, finally merging in 1865 into the 1st Arkansas Consolidated Infantry Regiment. The regiment has no connection with the 2nd Regiment, Arkansas State Troops, which participated in the Battle of Wilson's Creek, and is also separate from the 2nd Arkansas Consolidated Infantry Regiment, which was formed in 1864 from remnants of regiments surrendered at Vicksburg and Port Hudson.
