Pi Mu Epsilon (ΠΜΕ or PME) is the U.S. honorary national mathematics society.

[1] The society currently has chapters at 371 institutions across the U.S.[2] Pi Mu Epsilon was founded at Syracuse University on May 25, 1914, by Professor Edward Drake Roe, Jr.[3] Pi Mu Epsilon is dedicated to the promotion of mathematics and recognition of students who successfully pursue mathematical understanding.

[6] Pi Mu Epsilon's motto is Τὴν παίδευσιν καὶ τὰ μαθηματικὰ ἐπισπεύδειν or "To promote scholarship and mathematics".

The society also publishes a semi-annual journal, the Pi Mu Epsilon Journal, which both presents research papers particularly focusing on student authored papers, as well as a problem section.

[7] The Richard V. Andree Awards are given by the organization to undergraduates whose articles in the Journal have been judged as containing the best content for the year.
