Oneonta (/ˌoʊniˈɒntə/ OH-nee-ON-tə) is a city in southern Otsego County, New York, United States. It is one of the northernmost cities of Appalachia. Oneonta is home to the State University of New York at Oneonta and Hartwick College. SUNY Oneonta began as a normal school and a teacher's college in 1889, and Hartwick College moved into the city in 1928. The approximately 5,800 students from SUNY Oneonta and the approximately 1,500 students at Hartwick make up a significant percentage of the population of Oneonta. According to the 2020 U.S. Census, Oneonta had a population of 13,079. Its nickname is "City of the Hills." While the word "oneonta" is of undetermined origin, it is popularly believed to mean "place of open rocks" in the Mohawk language. This refers to a prominent geological formation known as "Table Rock" at the western end of the city.

The city is surrounded by the town of Oneonta, a separate municipal and political jurisdiction. Oneonta Municipal Airport (N66) is north of the city.

Indigenous ancestors of Algonquin and Iroquoian-speaking Native Americans inhabited the land in the territory of Oneonta before European colonists settled in the area. The Five Nations of the Iroquois Confederacy are believed to have emerged and gained dominance prior to the 15th century; they were in place at the time of early French and Dutch colonization.

The area's early European-American settlers did not arrive until around 1775 and consisted mainly of ethnic Palatine German and Dutch settlers moving out of the Hudson and eastern Mohawk valleys. The first such settler in the area now known as the Town of Oneonta was Henry Scramling (b. ~1743; d. 1808). He had secured a grant of 1,000 acres in the Susquehanna Valley, moved from German Flatts and settled about 1773 in the Oneonta Plains near the mouth of the Otego Creek. He left during the Revolution and returned after the conflict with his brothers, George and David Scramling, and his brothers-in-law, John and David Young. Their farms were not far from the mouth of the Otego Creek. The army led by General James Clinton passed through the area in order to join the Sullivan Expedition in 1779 against Iroquois settlements.

The first hamlet developed around 1800 and was later known as "Milfordville." In 1830, the Town of Oneonta was formed from parts of two other Towns in the county. Milfordville changed its name to Oneonta in 1832. In 1848, it was incorporated as a village within the Town.

In the mid-19th century, the Albany & Susquehanna Railroad reached Oneonta, soon after was leased in perpetuity to the Delaware & Hudson Canal Company. The arrival of the railroad stimulated development as a railroad center and attracting new industries. Oneonta was once home to the largest locomotive roundhouse in the world.

Dudley M. Campbell and Willard Vincent Huntington wrote accounts of Oneonta's history. In 1896, Edgar Luderne Welch's Oneonta Historical Souvenir was published covering the new normal school and other institutions in the community.

The village incorporated as a city in 1908. In February 1991 Mayor David Brenner of Oneonta, New York and Mayor Danny Hicks of Oneonta, Alabama officially recognized their cities as sister cities at a centennial celebration for Oneonta, Alabama.

Oneonta is located at 42°27′21″N 75°3′44″W / 42.45583°N 75.06222°W / 42.45583; -75.06222 (42.456003, -75.062302). According to the United States Census Bureau, the city has a total area of 4.4 square miles (11 km), all land.

The architecture of Oneonta consists of a variety of Victorian and 20th-century commercial and domestic styles, including low-rise commercial buildings. Oneonta currently has very few industrial complexes. Because of its location, Oneonta does not serve as a prime industrial city.

There are several historic buildings that were originally homes of prominent people. The Fairchild Mansion was placed on the National Register of Historic Places in 1974 and was formerly the home of George Winthrop Fairchild, one of the original partners with Thomas Watson. Fairchild and Watson were the founders of what eventually became IBM. Also, George I. Wilber House is a historic home located in the city. It was built in two phases, 1875 and about 1890. It is a three-story wood-frame structure on a stone foundation in the Late Victorian style. It features a three-story, round corner tower, cross gabled roof, and a large, very decorative wrap-around porch with a porte-cochere. In 1997 it became home to the Upper Catskill Community Council of the Arts (now the Community Arts Network of Oneonta). It was listed on the National Register of Historic Places in 2000.

Also listed on the National Register of Historic Places are: Bresee Hall, Chapin Memorial Church, Ford Block, Fortin Site, Municipal Building, Oneonta Armory, Stonehouse Farm, Oneonta Theatre, Old Post Office, Oneonta Downtown Historic District, and Walnut Street Historic District.
