Pi Delta Phi is the oldest academic honor society for a modern language in the U.S., having been founded in 1906 at the University of California, Berkeley. There are currently more than 389 chapters of the Society in the United States and two representative chapters at the American Universities in Paris and Aix-en-Provence.  The purpose of the Society is to recognize outstanding scholarship in the French language and its literatures, to increase the knowledge and appreciation of Americans for the cultural contributions of the French speaking world, and to stimulate and to encourage French and francophone cultural activities.

The Omicron Mu Chapter at the University of Colorado Denver was officially installed on campus on April 22, 2013.  Since then, regular induction ceremonies of students have been held honoring the excellence of our upper-division French students whose achievements meet the academic qualifications for regular membership into the honor society and those French students whose notable commitment to their French studies merits honorary status.
