The Medill School of Journalism (branded as Northwestern Medill; formally the Medill School of Journalism, Media, Integrated Marketing Communications) is the journalism school of Northwestern University. It offers both undergraduate and graduate programs. It frequently ranks as one of the top schools of journalism in the United States. Medill alumni include over 40 Pulitzer Prize laureates, numerous national correspondents for major networks, many well-known reporters, columnists and media executives. Founded in 1921, it is named for publisher and editor Joseph Medill.

Northwestern is one of the few schools embracing a technological approach towards journalism. Medill received a Knight Foundation grant to establish the Knight News Innovation Laboratory in 2011. The Knight Lab is a joint initiative of Medill and the McCormick School of Engineering at Northwestern, one of the first to combine journalism and computer science.
