Eaton Hall, University humanities building in Salem, Oregon, United States

Eaton Hall is a four-story hall of brick and stone with a composite shingle roof, built 1907–1908 on the north end of Willamette University's campus, beside Waller Hall to the west and Smullin Hall to the east. Its details mix Victorian, Gothic Revival and Beaux-Arts elements: pointed entrance arches, embedded towers or turrets, a rusticated stone foundation and decorative stone lintels. It houses the humanities departments.

Eaton Hall was built between 1907 and 1908 and dedicated on September 21, 1909, named for Abel E. Eaton, who gave $50,000 toward its construction. It held Willamette's law school from 1923 to 1938 and the university's administrative offices until 1980, when conversion to classrooms began. The interior was remodeled in 1983, the building joined Salem's Historic Properties List in 1984, and a $1.4 million attic conversion was finished in spring 2004.

The building houses several humanities departments where students and faculty gather daily for classes and seminars. The concentration of these programs in one location creates spaces for intellectual exchange across different disciplines.

The building is located at the northern edge of the campus and is easily accessible on foot. Visitors should know this is an active academic space where classes happen throughout the day.

The building exists because of a substantial donation from Abel E. Eaton, whose name it bears in recognition of his support. His financial contribution was essential to completing this construction project in the early 1900s.
