Ballston Spa is a village located in Saratoga County, New York, within the Capital Region of the United States. Situated southwest of Saratoga Springs, it serves as the county seat. The village was named in honor of Rev. Eliphalet Ball, an early settler and Congregationalist clergyman.
The village is positioned on the border of two towns, with its territory spanning both the Town of Ballston and the Town of Milton. According to the 2020 census, the population of the village was 5,111. While the village proper is often referred to locally as "The Village" or "Town," the name "Ballston Spa" is frequently used to describe the broader Ballston Spa School District, which encompasses most of the combined towns of Milton, Malta, and Ballston.
