Turtle Creek is a 21.1-mile-long (34.0 km) tributary of the Monongahela River that is located in Allegheny and Westmoreland counties in the U.S. state of Pennsylvania. Situated at its juncture with the Monongahela is Braddock, Pennsylvania, where the Battle of the Monongahela ("Braddock's Defeat") was fought in 1755.
During the mid-nineteenth century, the Pennsylvania Railroad laid tracks along the stream as part of its Main Line from Philadelphia to Pittsburgh.
