The Niagara Engine House is located on North Hamilton Street in downtown Poughkeepsie, New York, United States. It is a brick building constructed in the early 20th century, the only extant fire house of the six engine companies that once protected the city. It was designed by local architect Percival M. Lloyd in a late application of the Gothic Revival architectural style. In 1982 it, along with two other old Poughkeepsie firehouses, was listed on the National Register of Historic Places.
