Eaton Hall, Academic building at Tufts University, Medford, United States

Eaton Hall is a neoclassical building on top of Walnut Hill at Tufts University, designed by the New York firm Whitfield & King with red brick walls and marble columns and trim. Its main entrance has a pediment carried by four Corinthian columns on a marble slab, opening onto a hall with a grand staircase, a reading room and a lecture room on either side, and the stacks beneath the stairs.

Andrew Carnegie gave $100,000 in 1904 for a library on the Tufts campus, one of 43 he funded in Massachusetts. Construction ran from 1905 to 1908, and the collection moved from Ballou and Packard halls into four subject libraries for chemistry, engineering, physics-mathematics and religion. A 1949–50 wing by Arland A. Dirlam doubled the space; the collection outgrew the building in 1965, when Wessell Library was built next door.

The building contains a memorial wing with plaques dedicated to 102 Tufts students and alumni who died during World War II.

The building now houses departmental offices, classrooms, and a computer lab serving students and faculty. Visitors should keep in mind this is an active academic workspace where classes and meetings regularly take place.

Eaton Hall was one of 43 libraries Andrew Carnegie funded in Massachusetts, and one of the few that never carried his name. It honours Rev. Charles H. Eaton, a Tufts alumnus of the class of 1874 who presided over Mrs. Carnegie's wedding in New York in 1887.
