The Lumen is a high-rise apartment building in the Playhouse Square district of downtown Cleveland, Ohio.

It is the second new apartment building built in downtown Cleveland since the 1970s, following the construction of The Beacon in 2019.

Formerly a large surface parking lot located across from the Playhouse Square theaters, The Lumen is the fruition of a long-held vision of Playhouse Square and its former president and CEO, Art Falco, to turn the district into a viable residential community.

[3] Playhouse Square hired development manager Hines, builder Providence, Rhode Island–based Gilbane and international architectural firm Chicago-based Solomon Cordwell Buenz to complete the project.

[5] The floor plan includes 318 apartment units, 550 parking spaces, and 22,000 square feet (2,000 m2) of common space for residents, making it one of the largest apartment complexes in the city center.
