Chemung County is a county in the U.S. state of New York. The population was 84,148 as of the 2020 census.[2] Its county seat is Elmira.[3] Its name is derived from a Delaware Indian village whose name meant "big horn". The county is part of the Southern Tier region of the state.
Chemung County comprises the Elmira, NY Metropolitan Statistical Area, which is also included in the Elmira-Corning, NY Combined Statistical Area.
Many signs posted along roads in Chemung County refer to the area as "Mark Twain Country," because the noted author lived and wrote for many years in Elmira.
Chemung County was formed from 520sqmi of Tioga County in 1836.[4]
In 1854, Chemung County was divided and 110sqmi became Schuyler County, reducing Chemung to 410sqmi, its current size.[5]
In the late 1870s, the Greenback Party became prominent in Chemung and nearby counties in western New York. Here it was primarily allied with labor in a critique of capital, reaching its peak in 1878, the year following the Great Railroad Strike of 1877 and the Scranton General Strike in Pennsylvania. There were also strikes that year in Albany, Syracuse and Buffalo, starting with the railroad workers. In Steuben and Chemung counties, Greenbackers were elected to county councils in 1878 instead of Democrats, and others were elected from there and nearby counties to the state legislature, gaining votes of more than 25 percent in several of the Southern Tier counties. It gradually declined after that, due to internal dissension and the strength of the two major parties.[6]
According to the U.S. Census Bureau, the county has a total area of, of which is land and (0.8%) is water.[7]
