David McKee, an emigrant from Scotland, became in 1755 the first permanent white settler at the forks of the Monongahela and Youghiogheny rivers, the site of McKeesport. Around the time of the French and Indian War, George Washington often visited the area to see his friend Queen Alliquippa, a Seneca leader. On April 3, 1769, the colonial government granted McKee the exclusive right to run a ferry over the rivers, called McKee's Port. His son John took over the ferry and in 1795 laid out a town to be called McKee's Port, advertising lots in the Pittsburgh Gazette for $20 each and distributing them by lottery to avoid complaints about poor locations.

Then part of Versailles Township, McKeesport began to grow in 1830 with the mining of the region's large bituminous coal deposits, and its first schoolhouse was built in 1832, with James E. Huey as schoolmaster. It was incorporated as a borough in 1842, and its first steel mill opened in 1851. After the National Tube Works opened in 1872, McKeesport was for a time the fastest-growing municipality in the country, drawing families from other parts of the East and from Italy, Germany, Russia, Poland, Czechoslovakia and Hungary, most of whom worked at the tube works.
McKeesport became a nationally important steel center. In 1899 the National Tube Works joined twenty other pipemakers to form the National Tube Company, which in 1901 became part of U.S. Steel. The city also had a thriving Jewish community, the second-largest in Pennsylvania after Pittsburgh by 1919, peaking at about 6,850 people in the late 1930s.
