Update
was a small, unincorporated train station town in southwestern Pulaski County until being annexed into Little Rock in the late 1970s or early 1980s. The area today is part of Little Rock's seventh ward, while retaining 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. Its location on the south-central fringe of Little Rock proper — as well as proximity to unincorporated communities, neighborhoods in Southwest Little Rock and adjoining towns such as Shannon Hills which share the ZIP code — often leads to varying definitions of Mabelvale's boundaries.
