Leader Building, Classical Revival office building in downtown Cleveland, United States

The Leader Building is a 15-story, 199-foot (61 m) high-rise at the southwest corner of Superior Avenue and East 6th Street in Downtown Cleveland. Designed by Charles Adams Platt in the Beaux-Arts style, the limestone-clad structure contains 322,600 square feet (29,970 m2) of floor space and stands next to the Cleveland Arcade, across from the Cleveland Public Library.

The structure was completed in 1913 by industrialist Dan Hanna and initially served as headquarters for The Cleveland Leader newspaper. Later it housed the Cleveland News until that publication moved in 1926.

The Leader Building's name comes from The Cleveland Leader, the newspaper Dan Hanna bought and moved here in 1913; the paper folded in 1917, but his Cleveland News stayed until 1926. For 60 years the basement held the Colonnade Cafeteria, a lunch spot for downtown workers. Since 2017 the top twelve floors are the Residences at the Leader, and in 2025 the exterior stood in for the Daily Planet in the film Superman.

The building stands at the southwest corner of Superior Avenue and East 6th Street, next to the Cleveland Arcade and opposite the Cleveland Public Library. The ground floor is retail space, the second and third floors are offices, and the top twelve floors are the Residences at the Leader apartments, so the interior is not open to visitors. Architectural details of the limestone exterior can be seen from the street.

The basement housed the Colonnade Cafeteria for 60 years, where downtown workers came to eat their meals. This underground dining spot was a popular gathering place for employees throughout much of the 20th century.
