The Block Realty Building is a historic commercial building at 723 West Markham Street in Little Rock, Arkansas. It is a two-story structure, built out of steel and concrete, with a flat roof. It is supported by corten steel columns, with its first floor predominantly finished in glass, and the upper level in aggregate concrete tiles. It was built in 1964 to a design by architect-engineer Eugene Levy, and is a good local example of commercial Mid-Century Modern architecture.{{cite web|url=https://www.arkansasheritage.com/docs/default-source/national-registry/PU4550-pdf|title=NRHP nomination for Block Realty Building|publisher=State of Arkansas|accessdate=2019-09-02}}
