Saratoga Springs is a city in Saratoga County, New York, United States. The population was 28,491 at the 2020 census. The name reflects the presence of mineral springs in the area, which has made Saratoga a popular resort destination for over 200 years. It is home to the Saratoga Race Course, a thoroughbred horse racing track operated by the New York Racing Association, and Saratoga Performing Arts Center, a music and dance venue. The city's official slogan is "Health, History, and Horses".

The Mohawk Indigenous people used the area that is now Saratoga Springs as prime hunting ground, and some thought of the mineral springs as a gift from Manitou.

The British built Fort Saratoga in 1691 on the west bank of the Hudson River. During the early part of the 1700s, settlers from Europe began to develop the area. Shortly thereafter, British colonists settled the current village of Schuylerville approximately one mile south; it was known as Saratoga until 1831.

In 1767, William Johnson, a colonial British officer who was a hero of the French and Indian War, was brought by Native American friends to the spring to treat his war wounds. (In 1756, Johnson had been appointed British Superintendent of Indian Affairs in the Northeast region due to his success in building alliances with the Mohawk and other Iroquois nations. He had learned the language and created many trading relationships. He achieved great wealth from trading and landholdings, and was knighted for his service to the Crown with the Iroquois.)

The first permanent European-American settler built a dwelling in the area circa 1776. The springs attracted tourists, and Gideon Putnam built the first hotel for travelers. Putnam also laid out the roads and donated land for use as public spaces.

The Battles of Saratoga, the turning point of the Revolutionary War, did not take place in Saratoga Springs. Rather, the battlefield is 15 miles (24 km) to the southeast, in the Town of Stillwater. A museum dedicated to the two battles sits on the former battlefields. The British encampment before the surrender at Saratoga took place 10 miles (16 km) east of the city, in Schuylerville, where several historical markers delineate points of interest. The surrender of the sword of battle took place where Fort Saratoga had been, south of Schuylerville.^{[citation needed]}

Saratoga Springs was established as a settlement in 1819 from a western portion of the Town of Saratoga. Its principal community was incorporated as a village in 1826, and the entire region became a city in 1915. Tourism was greatly aided by the 1832 arrival of the Saratoga and Schenectady Railroad, which brought thousands of travelers to the famous mineral springs. Resort hotels developed to accommodate them. Patronage of the railroad increased after the Delaware and Hudson Canal Company assumed control in 1870 and began running the Empire State Express directly between New York City and the resort.

In the 19th century, doctor Simon Baruch encouraged the development of European-style spas in the United States as centers for health. Due to the presence of mineral waters Saratoga Springs was developed as a spa, generating the development of several hotels, including the United States Hotel and the Grand Union Hotel. The latter was, in its day, the largest hotel in the world.
