The Alexandra is a historic apartment building located on Gilbert Avenue in the Walnut Hills neighborhood of Cincinnati, Ohio, United States.

However, the rise of Thomas J. Emery's Sons saw a rapid increase in development in other neighborhoods: although Emery had participated in the downtown apartment boom, constructing the Lombardy Flats on Fourth Street to a Samuel Hannaford design, the firm made itself Cincinnati's leading apartment developer by building high-quality buildings along streetcar lines in the hillside neighborhoods above downtown, including Walnut Hills.

Its desirability was increased by its location near the end of the Gilbert Avenue streetcar line at the street's intersection with William Howard Taft, a significant east-west road, just one city block north of the commercial neighborhood of Peebles' Corner.

[2]: 14 Built of brick with a foundation of limestone and covered with a slate roof, the Alexandra is a Dutch Colonial Revival building constructed on the edge of the street, with no setback.

The same designation has been given to several other Emery apartment buildings, including the Brittany, Lombardy, and Saxony (all downtown), the Parkside in Clifton, and Haddon Hall and the Somerset in Avondale.
