Braddock is a borough located in the eastern suburbs of Pittsburgh in Allegheny County, Pennsylvania, 10 miles (16 km) upstream from the mouth of the Monongahela River. The population was 2,159 at the 2010 census. The borough is represented by the Pennsylvania State Senate's 45th district, the Pennsylvania House of Representative's 34th district, and Pennsylvania's 18th congressional district in the United States House of Representatives.
The town is named for General Edward Braddock (1695–1755). The Braddock Expedition, particularly his crossing of the Monongahela River on July 9, 1755 at this place, led to the British general's own fatal wounding and a sound defeat of his troops who had been moving against the French at Fort Duquesne. This battle, now called the Battle of the Monongahela, was a key event at the beginning of the French and Indian War.
The area surrounding Braddock's Field was originally inhabited by the Lenape, ruled by Queen Allequippa. In 1742, John Fraser and his family established the area at the mouth of Turtle Creek as the first permanent English settlement west of the Allegheny Mountains. George Washington visited the area in 1753-1754. It was the site of Braddock's Defeat on July 9, 1755.
