Central Music Hall (1879–1900) was a mixed-use commercial building and theater in Chicago, situated on the southeast corner of State and Randolph Streets. It was designed by celebrated German-born American architect Dankmar Adler. It was the first important building designed by the famous architect, in which he made initial use of his knowledge of acoustics. The building was demolished in 1900, around the same time Adler died, in order to build the Marshall Field & Company store, now Macy's.
