Dartmouth College fraternities and sororities

Dartmouth College is host to many fraternities and sororities, and a significant percentage of the undergraduate student body is active in Greek life. In the fall of 2022, 35 percent of male students belonged to a fraternity, and 36 percent of students belonged to a sorority. 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.

Social fraternities at Dartmouth College grew out of a tradition of student literary societies that began in the late eighteenth and early nineteenth centuries. The first social fraternities were founded in 1842 and rapidly expanded to include the active participation of over half of the student body. Fraternities at Dartmouth built dedicated residence and meeting halls in the early 1900s and 1920s, and then struggled to survive the lean years of the 1930s. Dartmouth College was among the first higher education institutions to desegregate fraternity houses in the 1950s and was involved in the movement to create coeducational Greek houses in the 1970s. Sororities were introduced to campus in 1977.

As of 2025, Dartmouth College extends official recognition to fifteen all-male fraternities, eleven all-female sororities, and three gender-inclusive Greek houses. The Greek houses are largely governed through three independent councils, the Interfraternity Council, the Inter-Sorority Council, and the Gender-Inclusive Greek Council. Dartmouth College has three cultural interest fraternities and three cultural interest sororities, which are governed through two additional councils: the National Pan-Hellenic Council and the Multicultural Greek Council. A chapter of the Phi Beta Kappa honor society is active, but there are no active professional fraternity chapters at Dartmouth College.
