The Carnegie Library, historically known as the Upland Public Library, is a Carnegie library located at 123 East D Street in Upland, California. Built in 1913, the library was the first public building in Upland. Architect Homer W. Glidden designed the library in the Classical Revival style. The library's design features a projecting central entrance with a plain frieze supported by two columns and brick pilasters, a stucco parapet extending around most of the building, and a cornice set above dentils. The building served as a library until 1969, when the library moved to a new building. The Upland Public Library still owns the building, which it uses to host events.
