The Russell Company Upper Mill is an historic structure in Middletown, Connecticut, built in 1836 and listed on the National Register of Historic Places. The building stands at the junction of Russell Street and East Main Street in South Farms. There is a small pond to the south. East Main Street's commercial and industrial development ends there. To the north, small businesses border the street, followed by the buildings of Russell Manufacturing Company, the area's most dominant feature. Russell Street crosses Sumner Brook nearby and ascends to a large residential district to the west. The mill is currently a condo-apartment complex.
