The Alexander Conner House is a historic rowhouse in Xenia, Ohio, United States.

Engaging in business there, he became prosperous enough to purchase a lot southeast of the county courthouse after twenty years of life in the city.

[2] The street-facing portions of the rowhouse are architecturally important to the city of Xenia: although the western and central buildings are Federal and the eastern is Greek Revival, they are together a typical example of housing found in many communities of southwestern Ohio before the Civil War of the 1860s.

In Xenia, no other historic rowhouses have survived to the present day, and almost no Federal streetfront houses are still in existence in the city except for the western and central components.

[2] In recognition of the importance of the architecture of the rowhouse, it was listed on the National Register of Historic Places on July 28, 1987; only the original three buildings qualified as contributing properties.
