The Spingler Building (also Springler Building or 5 Union Square West) is an eight-story Romanesque building at 5–9 Union Square West, between 14th and 15th Streets, in the Union Square neighborhood of Manhattan, New York City. Built in 1897 by William H. Hume & Son, it replaced a five-story building of the same name, which burned down in 1892. The Spingler Building occupies an L-shaped lot wrapping around 15 Union Square West to the north, and is also adjacent to the Lincoln Building to the south.
