The Martin Luther King Jr. Memorial Library (MLKML) is the central facility of the District of Columbia Public Library (DCPL), constructed and named in honor of the American civil rights leader Martin Luther King Jr. Its address is 901 G St. NW in Downtown Washington, D.C., with its main entrance between 9th and 10th St. on the opposite corner to Gallery Place station, and the Smithsonian American Art Museum.

[1] The city's previous central library, in Mount Vernon Square, was donated by industrialist Andrew Carnegie and dedicated in 1903.

[2] Architect Ludwig Mies van der Rohe designed the 400,000 square foot (37,000 m2) steel, brick, and glass structure, an example of modern architecture, in Washington, D.C.

[4] The building's lobby includes a large mural of Martin Luther King Jr. created by artist Don Miller.

The library follows accessibility regulations in accordance with Americans with Disabilities Act of 1990 (ADA): The Washingtoniana collection includes books, newspaper archives, maps, census records, and oral histories related to the city's history, with 1.3 million photographs from the Washington Star newspaper and the theatrical video collections of the Washington Area Performing Arts Video Archive.

[21] It was suggested that the auditorium be named after Bezos,[22] but this was criticised by council members including Charles Allen and D.C.'s shadow representative to Congress Oye Owolewa.
