Pi Mu Epsilon is a national mathematics honors society whose purpose is the promotion of scholarly activity in mathematics. The Pi Mu Epsilon Zeta chapter at UNC Wilmington has been in existence since 1974.

An initiation ceremony is held once a year in May. Membership in Pi Mu Epsilon is conferred as a reward for scholarly achievement in mathematics. It is by invitation, and based on guidelines set by the national office. The qualifications to be accepted into the society include the following: sophomores who are mathematics majors or who have an intent to major in math, with a 4.0 g.p.a for all mathematics courses taken, and who are in the top quarter of their class in general college work; juniors and seniors who have had two years of college mathematics including calculus and at least one 300 level course, a 3.0 g.p.a. for mathematical courses, and who are in the top one-third of their class in their general college work. Initiation dues are $22, which include a certificate. New members are inducted for life, and receive a one year subscription to the Pi Mu Epsilon journal.
