Hathorn Hall is a historic academic building on the campus of Bates College in Lewiston, Maine.

Bryant, it was the college's first academic building following the move of the Maine State Seminary (as it was then known) from Parsonsfield to Lewiston.

The hall is a rectangular brick building, three stories in height, with a hip roof capped by a cupola housing an open belfry.

Its main entrance, set on one of the short ends, is sheltered by a rectangular flat-roof portico, which has fluted Corinthian columns supporting a full entablature with cornice.

Nineteenth century "ivy stones" from early classes at the college are embedded in the brick along the exterior of the building.
