Swissvale is a borough in Allegheny County, Pennsylvania, United States, 9 miles (14 km) east of downtown Pittsburgh.

Named for a farmstead owned by James Swisshelm,[3] during the industrial age it was the site of the Union Switch and Signal Company of George Westinghouse.

John Swisshelm served under General George Washington in the Revolutionary War, and camped at Valley Forge.

Since 1874, the Allegheny Car & Transportation Shops had provided well-paying jobs to local citizens and were later purchased by George Westinghouse, the President of Westinghouse Air Brake Company, who formed the Union Switch & Signal company and maintained that facility in Swissvale.

(The area known as Regent Square also encompasses portions of Pittsburgh, Wilkinsburg, Edgewood, and Swissvale.)

Swissvale has voted for the Democratic party nominee overwhelmingly in the previous three general elections.
