Delaware County, colloquially referred to as Delco, is a county located in the U.S. state of Pennsylvania that borders Philadelphia. With a population of 562,960, it is the fifth most populous county in Pennsylvania, and the third smallest in area. The county was created on September 26, 1789, from part of Chester County, and named for the Delaware River.
Delaware County is adjacent to the city-county of Philadelphia and is included in the Philadelphia-Camden-Wilmington, PA-NJ-DE-MD Metropolitan Statistical Area. Delaware County is the only county covered in its entirety by area codes 610 and 484.
Delaware County lies in the river and bay drainage area named "Delaware" in honor of Thomas West, 3rd Baron De La Warr, Governor of the nearby English colony of Virginia. The land was explored by Henry Hudson in 1609, and over the next several decades it was variously claimed and settled by the Swedes, the Dutch, and the English. Its original human inhabitants were the Lenni-Lenape tribe of American Indians.
Once the Dutch were defeated and the extent of New York was determined, King Charles II of England made his grant to William Penn in order to found the colony which came to be named Pennsylvania. Penn divided his colony into three counties: Bucks, Philadelphia, and Chester. The riverfront land south of Philadelphia, being the most accessible, was quickly granted and settled. In 1789, the southeastern portion of Chester County was divided from the rest and named Delaware County for the Delaware River.
According to the U.S. Census Bureau, the county has a total area of 191 square miles (490 km2), of which 184 square miles (480 km2) is land and 6.8 square miles (18 km2) (3.5%) is water. It is the third-smallest county in Pennsylvania by area.
Delaware County is roughly diamond- or kite-shaped, with the four sides formed by the Chester County boundary to the northwest, the boundary with the state of Delaware (a portion of the "Twelve Mile Circle") to the southwest, the Delaware River (forming the border with the state of New Jersey to the southeast, and the city of Philadelphia and Montgomery County to the east and northeast.
The lowest point in the state of Pennsylvania is located on the Delaware River in Marcus Hook in Delaware County, where it flows out of Pennsylvania and into Delaware. The highest point in Delaware County is 500 feet at two points southeast of Wyola in Newtown Township .
Waterways in Delaware County generally flow in a southward direction and ultimately drain into the Delaware River. The waterways are, from west to east: the Brandywine River (forming a portion of the county's western boundary with Chester County), Naaman's Creek, Stoney Creek, Chester Creek, Ridley Creek, Crum Creek, Muckinipates Creek, Darby Creek and Cobbs Creek (forming a portion of the county's eastern boundary with Philadelphia). Crum Creek was dammed in 1931 near Pennsylvania Route 252 to fill Springton Lake (also known as Geist Reservoir), an approximately 391-acre (1.58 km2) drinking water reservoir maintained by Aqua America, the county's largest lake.
Delaware County is one of four counties in the United States to border a state with which it shares the same name (the other three are Nevada County, California, Texas County, Oklahoma, and Ohio County, West Virginia).
2,600 acres (11 km2) of the county are occupied by the Ridley Creek State Park.

It has operated under a home-rule charter with five at-large councilmembers since 1972. Republicans remain in control of many county council seats and row offices, despite the larger number of registered Democrats in the county. In the 2017 municipal election, Delaware County elected the first Democratic Council members and row officers since home-rule began. They took office in January 2018.
As of June 2017, there were 391,683 registered voters in Delaware County.
Until recent years, Delaware County was regarded as a strongly Republican county. The Delaware County Republican party political machine was controlled by William McClure and his son John J. McClure from 1875 to 1965. Delaware County voted for the Republican candidate in nearly every election from 1854 through 1988, with exceptions including the 1964 presidential election. In recent elections, however, Delaware County has voted for Democratic candidates in every presidential election since 1992, including voting for Bill Clinton in 1992 and 1996, Al Gore in 2000, John Kerry in 2004, Barack Obama in 2008 and 2012, and Hillary Clinton in 2016.
Delaware County has been trending Democratic, and the longstanding Republican registration edge has been erased. The Democrats now have over twice as many voters in the county as they had in 2002. It narrowly voted for Bill Clinton in 1992, but has gone Democratic in every Presidential election since then by 10 points or more by progressively-increasing margins. In the 2004 election Democratic presidential candidate John Kerry won the county by 14 points. In the 2008 presidential election, Democratic Senator Barack Obama defeated Republican Senator John McCain resoundingly, by over 21 points.
At the state and local level, however, Republicans still remain competitive with Democrats. Most Republicans from the county tend to be fiscally conservative and socially moderate, as is the case with Republicans from most suburban Philadelphia counties. In the 2004 US Senate election, Republican Arlen Specter defeated Joe Hoeffel but Democrat Bob Casey, Jr. defeated Rick Santorum in the 2006 Senate election. All three Democratic state row office candidates carried it in 2008. The Democrats presently hold all but one row office, though the Republicans currently have a majority on the county commission.
In 2016, Delaware County elected all Democrats in national office elections except Republican Patrick Meehan (U.S. Representative).
All of Delaware County is located in the state's 5th congressional district, represented by Democrat Mary Gay Scanlon. Prior to 2019, most of Delaware County had been in the 7th congressional district. The district had been held for 20 years by Republican Curt Weldon until he was ousted by Joe Sestak, a retired admiral, in the 2006 U.S. House of Representatives election. Also in the 2006 election, Democrat Bryan Lentz unseated Republican incumbent State Representative Tom Gannon in the 161st House district. In 2010 Sestak ran for the senate seat vacated by Arlen Specter and was replaced by Republican Pat Meehan, who defeated Lentz, the Democratic candidate. Lentz was replaced in the State House by Joe Hackett, a Republican. Meehan represented the 7th district until his resignation on April 27, 2018. Before it was thrown out by a Pennsylvania Supreme Court decision in 2018, the 7th Congressional District had been regarded one of the most irregularly drawn districts in the nation.
In the 2019 elections for the Delaware County Council, Republicans John McBlain and Colleen Morrone had served two terms and were not eligible for a third. Michael Culp, the council's third Republican, chose not to run. After a campaign described as having a good share of mud-throwing, Democrats swept the board and elected Monica Taylor, Elaine P. Schaefer, and Christine Reuther. This was the first time in history that the county had an all-Democratic county council.

They are eligible to apply for many competitive grants offered by the state and federal governments. There are two charter schools in 2011. They are located within the attendance borders of the Chester Upland School District. Charter schools may accept students from neighboring school districts.
