The Willimantic Freight House and Office is a historic railroad freight facility on Bridge Street in the Willimantic section of Windham, Connecticut. Built in 1870, the freight office, a fine example of Second Empire architecture, is now the only surviving element of the city's 19th-century railroad buildings; the freight house has been demolished. The buildings were listed on the National Register of Historic Places in 1982 as an important reminder of the city's importance as a major railroad junction in eastern Connecticut.
