List of fraternities and sororities at Cornell University
The Cornell University Greek system dates to the first months of university operation during the autumn of 1868. Cornell's co-founder and first president, Andrew Dickson White was a strong promoter of fraternities as a means of teaching self-governance to young students. Among its leaders, other strong supporters of the Greek system were Presidents Edmund Ezra Day and Frank H.T. Rhodes.
Among general ("social") organizations, Cornell currently recognizes 32 Interfraternity Council fraternities, 13 Panhellenic Association sororities, and 11 Multicultural Greek & Fraternal Council fraternities and sororities.

Multicultural Greek Letter Council
Sororities and Fraternities constituting the Multicultural Greek Letter Council (MGLC) were originally affiliated with specific ethnicities or languages. Most of these organizations are now fully integrated as are the rest of Cornell's Greek letter organizations. All MGLC chapters are. Listed with dates of local founding and national conference membership, these are men's and women's organizations that voluntarily coordinate their efforts within the MGLC. As part of MGLC or University self-governance during disciplinary action, chapters may be suspended ("de-recognized") for a time. Unless the suspensions result in long-term closure of the chapter or forfeiture of a building, they should not be removed from this list. Active groups in bold, dormant groups in italics. See the Office of Student Life for current MGLC members. The inter-Greek councils often cooperate on programs and policies, as do individual chapters from among the several Greek councils.

Honor, professional, and service societies
These organizations have a similarly long pedigree on the Cornell campus, but are largely non-residential. Members of the social and academic fraternities and sororities may join or be asked to join, as may non-Greek students. Multiple affiliations are allowable. The cut-off line where any campus organization falls within these headings or without is somewhat arbitrary; those formed prior to 1990 are listed under these subheadings in various volumes of the Baird's Manual of American College Fraternities, which for more than a century has been the data source of record for such organizations. Newer groups have been placed in categories which match Baird's categories. The latest, 1991 version of Bairds was published before the national development of some of the societies here, and therefore, position and inclusion is, in some cases, assumptive.
Honor and recognition societies
Honor societies recognize students who excel academically or as leaders among their peers, often within a specific academic discipline. Many honor societies invite students to become members based on scholastic rank (the top x% of a class) and/or grade point, either overall, or for classes taken within the discipline for which the honor society provides recognition. In cases where academic achievement would not be an appropriate criterion for membership, other standards are usually required for membership (such as completion of a particular ceremony or training program). These societies recognize past achievement. Pledging is not required, and new candidates may be immediately inducted into membership after meeting predetermined academic criteria and paying a one-time membership fee. Because of their purpose of recognition, most honor societies will have much higher academic achievement requirements for membership than professional societies. It is also common for a scholastic honor society to add a criterion relating to the character of the student. Some honor societies are invitation only while others allow unsolicited applications. Finally, membership in an honor society might be considered exclusive, i.e., a member of such an organization cannot join other honor societies representing the same field. Governance varies from faculty-guided to purely student run.
Listed by date of local founding with national conference membership, these are co-ed, non-residential, achievement-based organizations that self-select members based on published criteria.

Professional societies work to build friendship bonds among members, cultivate their strengths that they may promote their profession, and provide mutual assistance in their shared areas of professional study.
Listed by date of local founding with national conference membership, these are primarily co-ed and non-residential organizations, of an array of professional interests. Membership in a professional fraternity may be the result of a pledge process, much like a social fraternity, and members are expected to remain loyal and active in the organization for life. Within the group of societies dedicated to a professional field of study, for example, law societies, membership is exclusive; however, these societies may initiate members who belong to other types of fraternities. Professional Societies are known for networking and post-collegiate involvement. Governance varies from faculty-managed to purely student run.

Cornell University Residence Plan of 1966
During AY 1948-1949, Cornell University President Edmund Ezra Day formally distanced the University leadership from the increased discrimination which he observed at Cornell since 1910. His speech at the time marked the beginning an effort to end such unlawful practices, a goal to which the University remains committed. Following hearings into discrimination within Cornell's system of private fraternities and sororities, fifteen fraternities liquidated private holdings and entered into the Cornell University Residence Plan of 1966, or CURP'66, an agreement which required all signatories to refrain from unlawful discrimination. The majority of CURP ’66 houses are on the Cornell West Campus. The Plan created a system of 'living and learning' by Small Residence.
Each Group House was to be maintained by a Priority Group electing its Group Sponsor. Phi Kappa Psi, for instance, sponsored Group House No. IV d/b/a/ The Irving Literary Society, and developed its parcel on Cornell's West Campus. Cornell desired an academic atmosphere in student residence “units” providing appropriate facilities for intellectual and cultural activities and by encouraging student participation in these pursuits. CURP ’66 was not simply the creation of University-owned fraternities and sororities, but a plan to provide a supplement to the University-maintained dormitory complex, the existing Cornell Greek System, off-campus apartments and rooming houses. The vision was to organize “Small Residences” together, regardless of their national or local orientation as fraternities or cooperatives. The University program provided for no discrimination on the basis of race, creed, color or national origin. The issue of gender was addressed in the equal promotion of female, male and gender neutral Group Houses. In 1997, Cornell's president, Hunter Rawlings, reaffirmed the Board of Trustees' commitment to the Cornell University Residence Plan of 1966.
The current CURP ’66 was created from an existing University leasing system dating to the 1881 decision by Andrew Dickson White to favor fraternities over dormitories. White thought fraternities “’[would] arouse in the students a feeling of responsibility both for the care of the property and for the reputation of the house . . . [and] fastens upon [students’] duties and responsibilities similar to those of men in the active world was among the better solutions of the problems [of] . . . students in American universities.’”:33-34 White’s vision, in turn, develop from the professional analysis of American architect and planner, Frederick Law Olmsted, who saw the erection of residential clubhouses on Morrill Land-Grant Colleges Act as a reform over the barracks-like dormitories used by existing American universities and colleges. Like White, Olmsted felt clubhouses maintained by the students would form part of the educational experience. They were to be modeled on the typical rural household of the era, small country villas thought to avoid the negative aspects of the Industrial revolution.:21-23

- This small national was founded at Syracuse, placing its Beta Chapter at Cornell in 1915, which had been a local called Omicron Sigma Omicron, according to Bairds' Manual, 8th ed.
- The dormant Cornell chapter of Phi Beta Delta was absorbed in 1940 by the older Delta chapter of Pi Lambda Phi, welcoming its alumni into that fraternity.
- Sigma Omega Psi was a small Jewish fraternity that merged in 1940 with the larger Alpha Epsilon Pi. At the time of the merger, Cornell's chapter was dormant, it having been founded sometime after 1923 according to Baird's 10th edition. Sigma Omega Psi alumni were accepted into ΑΕΠ as a result of the merger.
- This small national was founded in 1920 at CCNY. Its Zeta chapter at Cornell merged into Phi Beta Delta in 1935.
- The 1933 Cornellian Yearbook lists Beta Psi, as accessed 20 Jan 2020. This was the Delta Alpha chapter of the fraternity. At dissolution, some members joined Beta Kappa. The Dec 1934 Omegan newsletter from Theta Upsilon Omega, accessed 20 Jan 2020, notes that the Alpha chapter of Beta Psi at Illinois had attempted a merger with Alpha Sigma Phi at the demise of its national, thus in 1934.
- This was the Theta chapter of θΚΦ during its existence, though its national was later renamed.
- Eleusis was founded as a local in 1912, becoming ΘΚΝ in 1931; only a few years later this small national merged with Lambda Chi Alpha.
- The short-lived Alpha Pi chapter of Beta Kappa didn't survive its mid-Depression founding. Six years later, in 1942 this national fraternity merged into Theta Chi, already present on the Cornell campus. Beta Kappa's 56 young alumni were accepted as alumni of Theta Chi.
- The Alpha Beta chapter of the small national fraternity Kappa Nu petitioned to join Phi Sigma Epsilon in 1962, having chosen not to participate in Kappa Nu's merger with Phi Epsilon Pi in 1961 as both fraternities (ΚΝ and ΦΕΠ) were then present on the Cornell campus. The resulting Phi Tau chapter of Phi Sigma Epsilon later was released (a second time) when that fraternity merged with Phi Sigma Kappa. National fraternity Phi Epsilon Pi itself later became part of Zeta Beta Tau.
- Cornell was the only campus where active chapters of both Phi Sigma Kappa and Phi Sigma Epsilon existed at the time of their merger in 1985. Rather than merge the chapters, Phi Sigma Epsilon's Phi Tau chapter was released to seek another national affiliation, and after a search, joined Theta Chi, also in 1985. To explain, two years prior, in 1983, Theta Chi on the campus had lost their charter due to rules violations, as noted in a historical piece from AEPi, accessed 14 Jun 2017. AEPi's campus history had noted this situation as the former (1983) Theta Chi members had been absorbed en masse into the AEPi chapter on the campus. The new, 1985 edition of Theta Chi (from Phi Sigma Epsilon) had no connection to the former Theta Chi chapter, but was granted its Lambda Chapter name and occupied its building. Meanwhile, Alpha Chi Omega sorority occupied the former Phi Sigma Epsilon chapter's former building, according to a local real estate blog at the time, accessed 14 Jun 2017. As a postscript, Theta Chi was again closed in 1999 due to drug use violations, and a 2003 recolonization attempt was unsuccessful.

- This small, now-dormant national was formed at Dartmouth in 1858, also known by the name Vitruvian. Its Beta Chapter was placed at Cornell. Not to be confused with the professional business fraternity of the same name.

- The 1889/90 Cornellian yearbook notes ΘΝΕ without a founding date, in a reference accessed 20 Jan 2020. This is in keeping with the affected secrecy of the group. Somewhat of a pariah, it was rejected by the NIC early in its life because of fears of membership drain of sophomores from other societies, and behavioral issues. Some time after Cornell's Delta chapter of the fraternity died, the national made efforts to reform and was eventually admitted into the NIC. Active dates from the Theta Nu Epsilon Wikipedia page.
