Erie County is a large urban county along the shore of Lake Erie in the western region of the U.S. state of New York, and the most populated county in New York State outside of the NYC Metro. As of the 2020 census, the population was 954,236. In 2025 the estimated population was 946,741. The county seat is Buffalo, which makes up about 28% of the county's population. Both the county and Lake Erie were named for the regional Iroquoian language-speaking Erie tribe of Native Americans, who lived in the area before 1654. They were later pushed out by the more powerful Iroquoian nations tribes. The county is part of the Western New York region of the state.
Erie County, along with its northern neighbor Niagara County, makes up the Buffalo–Niagara Falls metropolitan area, the second largest in the State of New York behind New York City. The county's southern part is known as the Southtowns.
History
When counties were established by the English colonial authorities in the Province of New York in 1683, present-day Erie County was inhabited by the Iroquois. Significant colonization by White Americans did not begin until after the United States had gained independence with the end of the American Revolutionary War in 1783. The U.S. forced the Iroquois to cede most of their lands, as many had been allies of the British during the conflict.
About 1800, the Holland Land Company, formed by American businessmen and their Dutch associates, extinguished aboriginal claims by purchasing the land from New York, acquired the title to the territory of what are today the eight westernmost counties of New York, surveyed their holdings, established towns and began selling lots to individuals. The state was eager to attract settlers and have homesteads and businesses developed. At this time, all of western New York was included in Ontario County.
As the population increased, the state legislature created Genesee County in 1802 out of part of Ontario County. In 1808, Niagara County was created out of Genesee County. In 1821, Erie County was created out of Niagara County, encompassing all the land between Tonawanda Creek and Cattaraugus Creek. The first towns formed in present-day Erie County were the Town of Clarence and the Town of Willink. Clarence and Willink comprised the northern and southern portions of Erie county, respectively. Clarence is still a distinct town, but Willink was quickly subdivided into other towns. When Erie County was established in 1821, it consisted of the towns of Amherst, Aurora, Boston, Clarence, Collins, Concord, Eden, Evans, Hamburg, Holland, Sardinia and Wales.
The county has a number of houses and other properties listed on the National Register of Historic Places listings in Erie County, New York.
In 1861, the hamlet of Town Line in the Town of Lancaster voted 85–40 to secede from the Union. Town Line never sought admission into the Confederate States of America and there is no evidence that men from the community ever fought for the Confederacy. Some reporting from that time indicates the vote was a joke. On January 24, 1946, as part of a nationally reported event, Town Line voted to officially return to the Union after 85 years of Union secession.

County government and politics
Prior to 1936, Erie County predominantly backed Republican Party candidates, with only four Democratic Party candidates winning the county in a presidential election - James Buchanan in 1856, George B. McClellan in 1864, Grover Cleveland in 1892 and Woodrow Wilson in 1912. However, starting with the 1936 election, it has turned predominantly Democratic since then, with only two Republicans carrying the county in a presidential election-- Dwight D. Eisenhower in 1952 and 1956 and Richard Nixon in 1972, with Nixon being the most recent. In 2016, like many other counties in the Rust Belt, Donald Trump expanded the Republican vote share thanks to his appeal to working-class whites and Ethnic-Catholic voters, keeping the margin in single digits for the first time since 1984. Four years later, in 2020, Joe Biden won 267,270 votes in Erie County, more than Barack Obama in 2008. Biden's margin of victory, however, was smaller than Obama's 2008 victory within the county and Trump's margin, though declining, was still higher than any Republican since 1988 (aside from his 2016 margin).

A 2003 Master Plan identified several broad categories of parks operated by the county, including heritage parks, waterfront parks, conservation parks, special purpose parks and forest management areas.
- Akron Falls Park (established in 1933, acquired by Erie County in 1947)
- Chestnut Ridge Park (established by Erie County in 1926)
- Como Lake Park (established in 1923, acquired by Erie County in 1926)
- Ellicott Creek Park (established by Erie County in 1926)
- Emery Park (established by Erie County in 1925)
Waterfront parks
Waterfront parks include the significant scenic sites and recreational trail systems along the county's Lake Erie shoreline.

Management of these lands is focused on natural resource conservation, in addition to potential commercial resource extraction of timber products or maple syrup.
