The U.S. Post Office in Ballston Spa, New York, is located on Front Street in the village's commercial center. It is a brick building constructed in the mid-1930s, serving the 12020 ZIP Code, which covers the village and the surrounding areas of the Town of Ballston.
Designed by Louis A. Simon, supervising architect of the Treasury Department, it uses an extremely restrained version of the Colonial Revival architectural style common on most post offices in small towns from that period. Only one other post office in New York is similar to it. In 1988 it was listed on the National Register of Historic Places.
