Connecticut Hall, New Haven

Connecticut Hall, formerly South Middle College, is a Georgian building on the Old Campus of Yale University. Completed in 1752, Connecticut Hall is the third-oldest of only seven surviving American colonial-era college buildings, and the second-oldest structure built for Yale College in New Haven.

Connecticut Hall is also one of the oldest buildings in Connecticut and the only remaining example of colonial-era architecture built at Yale University. It was designated a National Historic Landmark in 1965.

It was originally a student dormitory, a function it retained for 200 years. Part of the first floor became home to the Yale College Dean's Office after 1905, and the full building was converted to departmental offices in the mid-twentieth century. It is currently used by the Department of Philosophy, and its third story contains a room for meetings of the Yale Faculty of Arts & Sciences, the academic faculty of Yale College and the Graduate School.

Connecticut Hall's notable residents include:

- Nathan Hale, American Revolutionary War spy
- David Humphries, aide-de-camp to George Washington
- Noah Porter, president of Yale College
- Theodore Woolsey, president of Yale College
- Noah Webster, author of the first American dictionary
- Eli Whitney, inventor of the cotton gin
