The John Crerar Library /krəˈrɑːr/ is a research library, which after a long history of independent operations, is now operated by the University of Chicago. Throughout its history, the library's technology resources have made it popular with Chicago-area business and industry. Though privately owned and operated, the library continues to provide free access to the public for the purpose of conducting research in science, medicine and technology.

Established in 1894, the library which first opened to the public April 1, 1897, is named for John Crerar, who endowed the library, and who gained his wealth by founding a railroad supply firm.
