The Duke Energy Building (formerly the Cincinnati Gas & Electric Company Building) is a historic, 18-story, 269-foot-tall (82 m) structure in Cincinnati, Ohio. It was designed by Cincinnati architectural firm Garber & Woodward and John Russell Pope.

The neoclassical tower was completed in 1929 for the Cincinnati Gas & Electric Company and served as the company's headquarters until its merger with Duke Energy in 2006. From 1946 to 2011, CG&E sponsored an annual holiday model train display in the building's first-floor lobby.
