The Central Avenue Historic District is a small segment of the larger Grafton Hill neighborhood of Dayton, Ohio, United States.

Central Avenue is a prominent example of Dayton's earliest suburbanizing trends, having been built for people who were leaving the original boundaries of the city in and around what is now downtown, along the Great Miami River.

At this time, around the end of the 19th century and the beginning of the 20th, Dayton was undergoing rapid increases in population and commerce, due to unprecedented industrial growth.

[1] Since that time, the neighborhood has gained further recognition via community-organized walking tours and from Preservation Dayton, which recognized two homeowners for their restoration of the house at 330 Central Avenue.
