The W. E. Warren House is a historic house located at 196 Montgomery Street in Newburgh, New York. It is a focal point of the Montgomery—Grand—Liberty Streets Historic District, one of several houses in the area built by Calvert Vaux. A historical marker for Vaux's friend and partner Andrew Jackson Downing is located outside the house.

The Montgomery–Grand–Liberty Streets historic district was the first of two to be designated in the city of Newburgh, New York, United States. It runs along the three named north-south streets in the northeast quadrant of the city and includes 250 buildings in its 1,010 acres (4.1 km2). The later East End Historic District is nearby.
