Lehigh County is a county located in the Lehigh Valley region of the U.S. state of Pennsylvania. As of the 2010 census, the population was 349,497.  Its county seat is Allentown, the state's third-largest city behind Philadelphia and Pittsburgh.  The county, which was first settled around 1730, was formed in 1812 with the division of Northampton County into two counties. It is named after the Lehigh River, whose name is derived from the Delaware Indian term Lechauweki or Lechauwekink, meaning "where there are forks". 
Lehigh County is part of the New York City metropolitan area, but also borders the Delaware Valley and is a part of the Philadelphia media market. It is one of the fastest-growing counties in Pennsylvania.

The Lehigh Valley, which includes all of Lehigh and Northampton counties, is bounded on the north by Blue Mountain, a ridge of the Appalachian mountain range with an altitude of 1,300 to 1,604 feet (396 to 489 m), and on the south by South Mountain, a ridge of 700 to 1,100 feet (210 to 340 m) that cuts through the southern portions of the two counties. The highest point in Lehigh County is Bake Oven Knob, a mass of Tuscarora conglomeratic rocks that rise about 100 feet (30 m) above the main ridge of the Blue Mountain in northwestern Heidelberg Township. 
Lehigh County is in the Delaware River watershed. While most of the county is drained by the Lehigh River and its tributaries, the Schuylkill River also drains regions in the south of the county via the Perkiomen Creek and the northwest via the Maiden Creek.

Lehigh County and neighboring Northampton County are part of Pennsylvania's 15th Congressional district. The 15th Congressional district is a contentious swing district with neither Republicans nor Democrats winning the district consistently. Voters elected Republican Charlie Dent in 2004, 2006 and 2008 and, previously, Republican Pat Toomey in 1998, 2000, and 2002. In 2004, the county narrowly voted for John Kerry over George W. Bush for President, and in 2008 the county gave all statewide Democratic candidates significant leads and Barack Obama a victory of more than 15 points over John McCain, 57.1% to 41.5%. In 2012, President Obama carried the county again, but by a narrower margin: 53.17% to 45.52%. 
All five statewide winners carried it in November 2004. Although the Republican Party has historically been dominant in county-level politics, the Democratic Party has made substantial inroads this decade. In 2005, Bethlehem Mayor Don Cunningham unseated incumbent County Executive Jane Ervin to become the first Democrat to be elected to the office. Four of the nine commissioner seats and all row offices except for the District Attorney have held by Democrats since winning two at-large seats in November 2007. Lehigh County has a home-rule charter with four at-large and five district commissioners. In 2006 Lehigh County voters approved a county-charter amendment to combine the offices of Clerk of Courts, Register of Wills, and Recorder of Deeds into the office of the Clerk of Judicial Records. Clerk of Courts Andrea Naugle won the new office in November 2007.
