The Perry Street Historic District encompasses a fine collection of early-20th century architecture in Helena–West Helena, Arkansas. It includes fifteen buildings, arrayed on the single city blocks stretching south and west from the junction of Perry and Pecan Streets. The buildings on these blocks represent a cross-section of private and public architecture spanning 1880–1930, including two churches, the only synagogue in Phillips County, and the county's oldest public building, the 1879 Helena Library and Museum. Most of the residences in the district were built between 1900 and the 1920s. Although most of the residential architecture is Arts and Crafts in style, it includes two fine Queen Anne Victorians: the Moore House at 608 Perry and the William Nicholas Straub House at 531 Perry.
