Dartmouth College is host to many fraternities and sororities, and a significant percentage of the undergraduate student body is active in Greek life. In 2005, the school stated that 1,785 students were members of a fraternity, sorority, or gender-inclusive Greek house, comprising about 43 percent of all students, or about 60 percent of the eligible student body. Greek organizations at Dartmouth provide both social and residential opportunities for students and are the only single-sex residential option on campus. Greek organizations at Dartmouth do not provide dining options, as regular meal service has been banned in Greek houses since 1909.

St. Anthony Hall or the Fraternity of Delta Psi is an American fraternity and literary society. Its first chapter was founded at Columbia University on January 17, 1847, the feast day of Saint Anthony the Great. The fraternity is a non–religious, nonsectarian organization. In 1879, William Raimond Baird's American College Fraternities characterized the fraternity as having "the reputation of being the most secret of all the college societies." A 2015 writer for Vanity Fair says the fraternity is "a cross between Skull and Bones and a Princeton eating club, with a large heaping of Society and more than a dash of Animal House." Nearly all chapters of St. Anthony Hall are coed.
Delta Phi (ΔΦ) is a fraternal society established in Schenectady, New York on November 17, 1827. Its first chapter was founded at Union College, and was the third and final member of the Union Triad. In 1879, William Raimond Baird's American College Fraternities characterized the fraternity's membership as being largely drawn from the old knickerbocker families of New York and New Jersey. Today, the fraternity consists of ten active chapters along the East Coast of the United States, and also uses the names "St. Elmo," "St. Elmo Hall," or merely "Elmo" for its relation to Erasmus of Formia, the patron saint of sailors, and the Knights of Malta.
Fraternities and sororities exist for high school students as well as college students. Like their college counterparts, most have Greek letter names. Although there were countless local high school fraternities and sororities with only one or two chapters, many secondary fraternities founded in the nineteenth and twentieth centuries in the United States grew into national organizations with a highly evolved governing structure and regularly chartered chapters in multiple regions. Many of the local chapters of these national fraternities were not tied to individual high schools but were instead area-based, often drawing membership from multiple high schools in a given area.
