The Phi Beta Kappa Society honors students whose undergraduate academic records fulfill the objectives of a liberal-arts education. Founded in 1776, the society is the oldest and most prestigious honorary society in the nation. The UO has the only Phi Beta Kappa chapter in the Oregon University System.
Each year, the Phi Beta Kappa Society also elect six of the new inductees as the Oregon Six - the most outstanding at the University. Members of the Oregon Six are marked with O6.
