The School of Journalism & Mass Communication (or "J-School") is the journalism school of the University of Wisconsin–Madison. Located in Vilas Communication Hall, the School offers two undergraduate programs (BA Journalism and BS Journalism, both with reporting and strategic communication tracks), two Master of Arts programs in Journalism (Research and Professional), and a doctoral program (PhD Mass Communications) jointly administered with the Department of Life Sciences Communication.

The School is a pioneer in journalism education and a consistently top-ranked communication institution. It is one of the first to grant a doctoral degree in mass communication, and its PhD program has the reputation for producing leading scholars in the field, including Guido Stempel, Donald Shaw, Richard Perloff, Pamela Shoemaker, and Dietram Scheufele. Some notable alumni who won Pulitzer Prizes include Louis P. Lochner, photographer Neal Ulevich, Deborah Blum, Paul Ingrassia, and Anthony Shadid.

At present, the School offers more than 50 courses to nearly 500 undergraduate majors and about 100 graduate students. Administratively, it is under the College of Letters and Science. The School houses the world-renowned Mass Communication Research Center, as well as the Center for Journalism Ethics and the Wisconsin Center for Investigative Journalism.
