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 (489 m), and on the south by South Mountain, a ridge of 700 to 1,100 feet (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.

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.
