Theta Xi

Founded in 1885, the Delta Chapter of Theta Xi is the second oldest fraternity at MIT. We currently have 25+ active brothers who are all deeply involved with MIT academics and extracurricular activities, such as HackMIT, varsity athletics, and many others.


The brothers hail from as close as Boston and as far as Malaysia and Bulgaria, and span a variety of majors and interests. Our house spans a wide range of majors from physics to political science, with many pursuing UROPs, internships, and startups outside of the classroom. We relax by grabbing boba, playing video games and board games, watching movies, and adventuring into Boston. Our brothers are also committed to our community, participating in volunteer efforts such as cleaning up the Charles River and DynaMIT.

Our house is a fifteen-minute walk across the Harvard Bridge from campus. Brothers often describe the walk back to the house after classes as a trip back home after a long day of work. It encompasses two addresses, 64 and 66 Bay State Rd., and is located at the heart of Kenmore Square, just under the Citgo sign. Positioned close to Kenmore Square, the MBTA, Fenway Park, and Newbury Street, there is always plenty to do within a short walk's distance.

The house itself consists of two beautiful brownstone mansions. The four-story houses feature sixteen bedrooms, which can comfortably accommodate up to thirty-seven brothers. The houses also include a library, a pool/ping-pong room, and a makerspace in the basement. In the past two years, we have also renovated our bathrooms and our front patio. Dinner in the house is catered five nights a week.
