The county is named for Continental Army General Hugh Mercer, who died at the Battle of Princeton in 1777.

Officially founded in 1838 and carved out of other surrounding counties, Mercer County has a historical impact that reaches back to the pivotal battles of the American Revolutionary War. On the night of December 25, 1776, General George Washington led the American forces across the Delaware River to attack Hessian forces in Trenton, New Jersey, who did not anticipate an attack near Christmas. Washington followed up the assault with a surprise attack on General Charles Cornwallis' forces in the Battle of Princeton on the eve of January 2, 1777, eventually retaking the colony. The successful attacks built morale among the pro-independence colonists.

Mercer County also has the dubious distinction of being the famed landing spot for a Martian invasion of the United States. In 1938, in what has become one of the most famous radio plays of all time, Orson Welles acted out his War of the Worlds invasion. Wells landed his imaginary aliens on Mercer County soil, using what is now West Windsor Township as the point of first contact. A monument commemorating the "landing" is erected at Grover's Mill
