The Carnegie Free Library of Allegheny is situated in the Allegheny Center neighborhood of Pittsburgh, Pennsylvania.

Donated to the public by entrepreneur Andrew Carnegie, it was built from 1886 to 1890 on a design by John L. Smithmeyer and Paul J. Pelz. The library and musical conservatory was built of red and grey granite from Maine. The contractor was Vinalhaven, Maine's Bodwell Granite Company, which had furnished granite for major public works including the State, War and Navy Department building in Washington, DC., now called the Eisenhower Executive Office Building.It did not open until 1890 thus making it the second Carnegie library to open. The first one to open being the Carnegie Free Library of Braddock, built for steel-workers in Braddock, 9 miles up the Monongahela River from Pittsburgh. The building also features the first Carnegie Music Hall in the United States. The Music Hall at the Braddock Library would not open until an 1893 expansion of that structure.
