St. Anthony Hall

St. Anthony Hall, also known as Saint Anthony Hall and The Order of St. Anthony, is a national college literary society also known as the Fraternity of Delta Psi (ΔΨ) at elite colleges in the United States of America. St. Anthony Hall's activities foster the social and intellectual development of its undergraduate members by encouraging individual expression, promoting the exchange of ideas by providing a forum for discussion and presentations. At several of its chapters, St. Anthony Hall hosts public lecture series. The first, or 'Alpha' Chapter was founded at Columbia University on January 17, 1847, which is the feast day of St. Anthony.

In 1879, Baird's Manual characterized the organization as having "the reputation of being the most secret of all the college societies." References appear in several F. Scott Fitzgerald short stories, Tom Wolfe's novels, and the Order has a distinguished architectural inheritance. The organization is often referred to as St. A's or the Hall. It has no official religious affiliation.
