The Phi Beta Kappa Society is an academic honor society with the mission of "fostering and recognizing excellence" in the undergraduate liberal arts and sciences. Founded at the College of William and Mary on December 5, 1776, it is the oldest such society in the United States. The University of Wyoming chapter formed in 1926 and was granted a charter in 1938.
