List of MIT fraternities and sororities

The following is a list of MIT's fraternities, sororities and independent living groups.


Many MIT fraternities are located in Boston because the Institute was originally located in the Back Bay neighborhood, and had no dormitories to house its students.

MIT moved to its current Cambridge campus in 1916, and newer independent living groups have sprouted up or moved in around it.

From the 1860s through the first half of the 1900s, MIT students were almost entirely male. In the 2000s, the Institute's undergraduate gender ratio reached nearly 50-50. A period of demographic and political change in the 1960s and 1970s, which followed larger national trends, resulted in the conversion of several all-male, nationally affiliated living groups into local co-ed groups, and led to the expansion of all-female and co-ed housing options.

Residence Selection

Traditionally, rush at MIT occurred during "Residence/Orientation" (R/O) Week, which was the final week of each summer before the start of the fall semester. All incoming freshmen and transfer students would arrive on campus a week before Registration Day, the official start of the fall semester. During R/O Week, the incoming class would participate in orientation activities, take the so-called "writing test" to attempt to test out of the MIT Writing Requirement, and participate in residence selection. All students were free to participate in fraternity, sorority and independent living group rush. Those students who did not end up in an off-campus living group would also participate in the dorm selection process (see "List of Massachusetts Institute of Technology undergraduate dormitories").

FSILG rush was an intense experience for all involved, cramming the entire process of choosing among dozens of housing options into essentially three days. It always began with an event known as the "Killian Kickoff," held in Killian Court in the middle of campus. MIT's president would deliver a welcoming speech to the incoming class, which always ended with, "Let the rush begin!" Immediately, upperclassmen removed their overshirts to display their letters (an upperclassman wearing anything which identified his or her living group prior to the start of rush was a serious violation of rush rules), and fanned out through the crowd in search of freshmen. For the incoming students, rush was a whirlwind of cookouts, parties and field trips all over the Boston area. For the upperclassmen, it was a marathon of 18 hour days, trying to meet as many freshmen as possible while competing with other living groups for the most popular prospects. For both sides, rush could be stressful, exhausting, and highly emotional. In many ways, rush was a microcosm of the broader MIT experience.

The old rush was supported behind the scenes by the 24-hour week-long "R/O Clearinghouse", a system for keeping track of freshman students as they threaded their way through a maze of fraternity rush events interleaved with other MIT orientation activities. Whenever a freshman "checked into" or "checked out of" a fraternity activity, that frat's R/O liaison person was supposed to call the R/O Clearinghouse to update what was essentially a real-time database to track the whereabouts of the new students. R/O Clearinghouse physically consisted of a bank of telephones staffed by volunteers in a large room equipped with computer terminals, located in the MIT EECS Department. The volunteers were drawn from MIT service fraternities and dorm residents who were supposed to be "impartial" with respect to the different competing fraternities. The dorm volunteers were motivated at least in part by the knowledge that an unsuccessful fraternity rush would result in even greater overcrowding of the MIT dormitory system. which simply lacked the physical space to accommodate every new student.

Freshman housing rush was eliminated in an initiative led by MIT president Charles Vest in the wake of the September 1997 death of Fiji (Phi Gamma Delta, since disbanded at MIT) freshman Scott Krueger.[1] Beginning with the 2002 - 2003 academic year, all freshmen were required to live on campus. This was made possible by the completion of a new undergraduate dorm which opened that year, Simmons Hall. Since then, MIT has continued to build or renovate more dormitories, including an expansion of choices for graduate students as well (see "List of Massachusetts Institute of Technology graduate dormitories").

A much-toned-down echo of the old rush still occurs with the so-called "dormitory rush" process, in which new students decide their dormitory preferences, based in part upon special events staged by various dorms to introduce newcomers to their distinctive living arrangements. However, dormitories do not "choose" which new students to admit, but can only influence prospective new members to express greater or lesser preference for specific dorms on their respective entries in the dorm lottery process. Pressure to quickly find housing has been lifted by MIT's guarantees that every freshman student will find space in an on-campus dorm, and that undergraduate students can remain in the dorm system for up to 4 years. The old fraternity rush has been depressurized, with recruiting spread out throughout the first academic year, and less frantic rush events for prospective new members.

The Action Man

The Action Man (MIT) was a mysterious fixture of the MIT fraternity scene from the mid-1970s through the early 1990s. He was known for calling MIT fraternities, offering "some action" to anyone who would talk to him.


Alpha Delta Phi

The Lambda Phi chapter of the Alpha Delta Phi fraternity is located at 351 Massachusetts Avenue, Cambridge, MA. The chapter was founded in 1976 through the assistance of the brothers of the Lambda Phi fraternity, which was a local fraternity at MIT from 1906 to 1925. That was a literary fraternity that had unsuccessfully petitioned to join the Alpha Delta Phi international. Their petition had been rejected because ADP considered MIT at that time to be an engineering trade school and so not compatible with their literary tradition. Henry Leeb, MIT'1915 remained friends with members of ADP, but died only 3 weeks after the current chapter was approved.

Sigma Nu

The Formation of Delta Pi

Delta Pi was formed in April 1990 as a local fraternity to continue the brotherhood experienced by the members of the Mu Tau Chapter of the Alpha Epsilon Pi fraternity. A house was acquired for the new fraternity in the spring of 1991 and members began moving into the house during the summer of that year. Rush 1991 proved successful for Delta Pi as seven men pledged but the following year the house became not financially viable. Members moved to apartments in Boston and Cambridge. At this point members also decided to cancel fall Rush because of their doubt in the fraternity’s future. Another reason was that the move out of the house in Boston fell on the same weekend as Rush, making it impossible to accomplish both tasks at the same time. The fall of 1992 proved to be a turning point as the younger members decided that the ideals of the fraternity were extremely important and must live on. With this new direction the fraternity looked at several options. One of the options was to affiliate with a national fraternity.

Affiliation with Sigma Nu

The decision to affiliate with Sigma Nu came after much research and discussion. It was decided that the stability of a national fraternity would aid in maintaining the brotherhood. Sigma Nu was the first choice of the members and they expressed interest in rechartering the Epsilon Theta Chapter. With this as their goal, the members of Delta Pi formally disbanded and became the MIT Colony of Sigma Nu. Throughout the fall of 1994 the members of the MIT Colony worked on preparing a petition to send to Sigma Nu National requesting a charter. This document was completed later that year and was officially submitted to Sigma Nu on December 4, 1994. On April 22, 1995, Sigma Nu officially rechartered the Epsilon Theta Chapter (#100) at MIT. Brothers from the Zeta Eta Chapter at Tufts University initiated the first members and the chapter was once again active.

The Sigma Nu chapter house, located at 28 Fenway in the Back Bay Fens, is currently home to 40 brothers.

Independent Living Groups

MIT is somewhat unusual in having a set of officially recognized living groups which are neither dormitories nor fraternities or sororities - these are known as Independent Living Groups. (Hence the acronym "FSILG" to describe Fraternities, Sororities, and Independent Living Groups.) ILGs operations are similar to a typical fraternity houses, but without the Greek affiliation and rituals, and in some cases with a philosophy based on the idea of a housing cooperative.

In the 2000s, the Inter-Fraternity Council decided to focus on male, Greek houses only, and the ILGs formed the independent student government organization, the Living Group Council. All FSILGs alumni corporations (usually the legal entity which owns the physical house, distinct from the mainly undergraduate student government entities which govern each house) are still members of the Association of Independent Living Groups.[6]

The term "Independent Living Group" is sometimes used to refer to all FSILGs, because they are all independent of MIT.

Epsilon Theta

Epsilon Theta is a co-ed local fraternity located in Brookline, Massachusetts. (It is listed as an ILG because it is a member of the Living Group Council.) It is one of two local co-ed fraternal living groups, along with No. 6.

ET was originally the Epsilon Theta chapter of the national Sigma Nu fraternity. It split from the national in the 1970s, not long after it became co-ed. It is not affiliated with the present-day MIT chapter of Sigma Nu, which was formed in the 1990s.

Fenway House

Fenway House is a co-ed cooperative living group located on Fenway House website.

Number Six Club

The Number Six Club is the Tau Chapter of Delta Psi, a nationally affiliated literary fraternity. It is also the only nationally-affiliated co-ed residential fraternity on MIT campus. (Epsilon Theta is a local co-ed fraternity, and Alpha Phi Omega is a co-ed service fraternity.) The fraternity is more commonly known in its other chapters as St. Anthony Hall.

The house is now situated in Cambridge, on the MIT campus along "Dorm Row". It is home to over 40 members from around the world. The four-story, ivy-covered house is owned and operated by its own members.

  • The No6 Club


pika is a co-ed housing cooperative located in Cambridgeport, a neighborhood of Cambridge.

It was founded in 1970 as a chapter of the national all-male Housecorp.

"pika", when referring to the ILG, is always written with a lowercase p. It is unrelated to the animal known as the pika.
