The St. Thomas More Society (STMS) is a student group focused on incorporating Catholic identity into the legal profession. The purpose of STMS is to promote faith and fellowship among students who desire to learn more about how Catholicism operates in both their personal and professional lives.

Activities of STMS include "Thomas More Tuesday" luncheons which involve conversations about faith, life, and the law. In addition, there are opportunities for spiritual growth, including guided rosaries, Mass attendance, and activities related to observing holy days of obligation.

STMS is open to all law students, faculty, and staff of the University of Wisconsin-Madison, regardless of faith/ spiritual identity, according to UW-Madison Non-Discrimination Policy.
