Mabelvale was a small, unincorporated train station town in southwestern Pulaski County, Arkansas, until being annexed into Little Rock following a special election that was held on May 3, 1973. The area today is part of Little Rock's seventh ward, although it retains a separate postal designation and ZIP code from most of the rest of the city. The neighborhood is currently represented on Little Rock's City Board of Directors by Brenda "B.J." Wyrick.
The neighborhood is generally defined as the homes and businesses in the immediate area surrounding the intersection of Mabelvale Main Street and the Union Pacific railroad line. However, its location on the southwestern fringe of Little Rock proper — as well as its proximity to unincorporated communities, to other neighborhoods in Southwest Little Rock, and to adjoining towns such as Shannon Hills which share the ZIP code — often leads to varying definitions of Mabelvale's boundaries. Even so, most would agree that the area generally referred to contemporarily as Mabelvale spans multiple counties: while primarily located in Pulaski County, some of its areas spill over into neighboring Saline County.
