It was originally designated as the 39th Arkansas, but later redesignated as the 30th Arkansas Infantry Regiment.

Local tradition notes that a funding drive to construct the university promised to name it after the major contributor.  Allegedly, James H. Lane made the largest pledge, received the namesake honor, and then died of a self-inflicted gunshot wound before he could carry out his promise.

The 18th Arkansas Infantry (Marmaduke's) (1861–1865) was a Confederate Army infantry regiment during the American Civil War.  The unit was also briefly identified as the 1st Arkansas Infantry Battalion.  The unit was most often referred to as the 3rd Confederate Infantry Regiment.  The designation "Confederate Infantry Regiment" was intended to convey the difference between Provisional Confederate Army units and Regular Confederate Army Units, with Provisional units being those regiments who received a state designation such as "XX Arkansas Infantry Regiment".  In practice, the designation was most often utilized when Regiments were assembled utilizing companies from more than one confederate state.  The "3rd Confederate Infantry Regiment" is occasionally misidentified as the 3rd Arkansas Infantry Regiment commanded by Colonel Van H. Manning.
