Centre County comprises the State College, PA Metropolitan Statistical Area. The county is part of the Central Pennsylvania region of the state.

The lands of the future Centre County were first recorded by James Potter in 1764. Potter, having reached the top of Nittany Mountain, and "...seeing the prairies and noble forest beneath him, cried out to his attendant, 'By heavens, Thompson, I have discovered an empire!'" After the American Revolutionary War, Centre County was created on February 13, 1800, from parts of Huntingdon, Lycoming, Mifflin, and Northumberland counties; it was named for its central location in the state.

According to the U.S. Census Bureau, the county has a total area of 1,113 square miles (2,880 km), of which 1,110 square miles (2,900 km) is land and 3.0 square miles (7.8 km) (0.3%) is water. Centre County is one of the 423 counties served by the Appalachian Regional Commission, and it is identified as part of the "Midlands" by Colin Woodard in his book American Nations: A History of the Eleven Rival Regional Cultures of North America. It is the fifth-largest county in Pennsylvania by area and uses area code 814.

Centre County had for many years been a strongly Republican county, like most of rural Pennsylvania. In the early 21st century, however, it has been more competitive. In 2000 George W. Bush defeated Al Gore with 52% of the vote to Gore's 43%. In 2004 Bush won the county by a much smaller margin. Bush won 51% to Kerry's 47%, a margin of only 4%. In 2006, Governor Ed Rendell and Bob Casey Jr. both carried Centre, and Democrat Scott Conklin decisively won the State House seat left open by the retirement of Republican Lynn Herman in the 77th district. In 2008, Democrats captured the countywide registration edge, Barack Obama carried the county with 55% of the vote to McCain's 44%, and Democratic statewide winners (Rob McCord for Treasurer and Jack Wagner for Auditor General also carried Centre).

In 2012, Barack Obama won the county in his reelection campaign by a very narrow margin, 48.9% to 48.65%, a difference of just 175 votes. In 2016, Democrat Hillary Clinton beat Republican nominee Donald Trump 47.76% to 45.86%. In that same election, incumbent Republican Senator Pat Toomey beat Democratic opponent Katie McGinty 47.91% to 46.2% in the county.
