The J. S. Halpine Tobacco Warehouse is a historic tobacco warehouse at West and Mill Streets in New Milford, Connecticut. It is a 5-1/2 story brick structure, located just south of downtown New Milford adjacent to the railroad tracks. It has a two-stage roof that is mostly gabled, with a slight gambrel. It was built c. 1900-02, at a time when this region of the Housatonic River valley was a major tobacco production region, and is one of the few buildings left in New Milford that is associated with that business and time period. The property was used for tobacco sorting and curing until that business collapsed in the late 1930s.
