St. Elmo Society is a secret society at Yale University. It was founded in 1889 as an independent entity for seniors within the nationally chartered fraternity, Delta Phi (&Delta &Phi), Omicron Chapter (1889-1925).

St. Elmo is a non-profit organization that provides supplementary education to its members through various activities and interactions. It is the hope that these methods will inspire new meaning to the students’ Yale education. In return, the delegation must commit itself to by-laws, rules, and guidelines set forth by the Corporation’s Board of Governors.
